In modern timesSexIn the field of sexual intercourse, sexual techniques are not merely physical interactions; they are the perfect fusion of emotion and physiology. Among these, "S-shaped sexual penetration," as an advanced sexual pattern, emphasizes the curvilinear movement of the penetration path, simulating an S-shaped trajectory to achieve deeper stimulation and pleasure. This technique, inspired by ancient Eastern erotic texts and incorporating modern physiological and psychological research, aims to enhance intimacy and satisfaction between partners.
The basic concept of S-shaped sexual penetration
Definition and origin
S-shaped sex refers topenisor toy insertionvaginalWhen inserting the penis (or anus), the thrusting path presents an S-shaped curve motion rather than a straight line in and out. This is similar to the rhythm of waves, combined with fine adjustments of front and back, up and down, left and right, to simulate the bends of natural water flow. The origin of the technique can be traced back to ancient China.The Art of Sex,like"Su Nu Jing》Nine shallow and one deep"Variations, but the S-shape pays more attention to the changes in spatial curves.
In practice, S-shaped thrusting requires the male (or active party) to control the coordination of waist and hips, so that the insertion goes from shallow to deep, and then withdraws in an S-shaped twist. This technique is suitable for various positions, such as missionary,Girl on topOr doggy style. The key is "fluidity" and "variability," avoiding mechanical repetition.
Physiological basis
From a physiological point of view, the inner wall of the vagina is full of nerve endings. The G-spot (about 5-8 cm on the front wall) and the A-spot (deep near the cervix) are sensitive areas. S-shaped thrusting can stimulate multiple points: shallow thrusting can touch the labia andclitoris, while the depth is higher, impacting the deep tissue. This change can increase blood circulation, improve lubrication and reduce discomfort.
Psychologically, S-shaped thrusting creates an "anticipation and surprise" effect. Eye contact and breathing synchronization between partners can strengthen emotional connection.DopamineRelease: Straight-line thrusting can easily lead to habitual numbness, while S-shaped changes stimulate neural diversity and prolong the duration of pleasure.
Detailed description of depth changes
Classification of depth
The core of S-type thrusting is the change in depth. The insertion depth is divided into three levels:
- Shallow (1-5 cm): Only touches the vaginal entrance, stimulating the clitoris and vulva. Suitable for foreplay to increase excitement.
- Moderate (5-10 cm): Touching the G-spot and combining it with S-shaped twisting can produce a strong sense of contraction.
- Depth (more than 10 cm): Impacts the cervix, suitable for sprinting before orgasm, but attention should be paid to the comfort of the partner.
Change mode:Light-Medium-Deep-Medium-Light" is the basis of the cycle, and is integrated into the S-shaped path. For example, when insertingUpper left corner curvedEnter, exitTwist the lower right cornerThis variation can avoid fatigue caused by a single stimulus.
Practical steps
- Preparation: Ensure adequate lubrication, use lubricant or foreplay. Communicate comfort levels with partners.
- Initial thrusting: Start from shallow depth, enter slowly in an S shape, and observe the reaction.
- Change Adjustment: Change the depth every 10-15 thrusts. For example, 5 shallow thrusts, 3 medium thrusts, and 1 deep thrust.
- Monitoring reactions: Pay attention to your partner'smoan, muscle tension, adjust the amplitude.
The reason: The changes in depth and shallowness simulate a natural rhythm, similar to the rise and fall of a heartbeat, synchronizing physiological responses. Data shows that the orgasm rate for those with no changes in penetration is only 401 TP3T, while that for those with changes is 751 TP3T (according to the European Journal of Sexual Health).
Time arrangement and control
Time period
S-shaped thrusting emphasizes time management, dividing the sexual process into multiple stages, each with specific depth and rhythm. The recommended total duration is 30-60 minutes, depending on your physical strength.
- Phase 1: Foreplay and light introduction (0-10 minutes)
Focus on shallow, S-shaped thrusts at a slow speed (1-2 times per second). Purpose: Build excitement and increase lubrication. Deep/Shallow Ratio: 90% shallow, 10% medium.
Reason: Avoid excessive stimulation in the early stages to prevent discomfort. Data: This stage can increase vaginal moisture by 20-30 %. - Phase 2: Moderate Exploration and Variation (10-25 minutes)
Introduce a moderate S-type movement, alternating shallow, medium, and deep movements. Use a moderate speed (2-3 times per second). For example, cycle through shallow and deep movements every 5 minutes.
Reason: Stimulate the G-spot and accumulate pleasure. Studies show that dopamine levels rise 50% during this stage. - Phase 3: Deep Sprint and Climax (25-40 minutes)
Increasing the depth ratio (50% deep) will increase the S-shape amplitude. The speed is fast (3-4 times per second), but there are intermittent pauses.
Reason: Impacting deep sensitive areas, triggering orgasm. Data: Prolonging this phase can increase the probability of multiple orgasms 30%. - Phase 4: Post-play and cool-down (40-60 minutes)
Return to shallow depth and exit slowly. Include hugs and massage.
Reason: Helps recovery and strengthens emotions. Ignoring the aftermath will result in a 15% decrease in satisfaction.
Time control skills
Use a timer or music to help. Why: Time management prevents premature endings and optimizes energy allocation. According to the Harvard Sexual Health Study, structured time improves overall satisfaction.

Cause Analysis
Physiological reasons
- Neurostimulation diversity: S-shaped changes activate more neurons and reduce habituation. Reason: The brain prefers novel stimulation.
- Improved blood circulation: Alternating deep and shallow massage promotes vaginal congestion and increases sensitivity. Data: Blood flow increased by 15-20%.
- Hormone release: Oxytocin and endorphin peaks occur during the transition phase, strengthening the connection.
Psychological reasons
- Emotional enhancement: Time period control makes partners feel valued and reduces anxiety.
- Confidence boost: Those who master the skills have a 30% increase in sexual satisfaction (data from the Journal of Psychology).
- Preventing monotony: Reason: In long-term relationships, variety is key to maintaining passion.
Potential risks and causes
Excessive depth may cause discomfort. This is due to individual differences. Communication and practice are recommended. Data: 51 TP3T users reported mild pain, which resolved after adjustment.
Advanced Techniques and Variations
Postural Integration
- Missionary: Easy to control S shape, suitable for beginners.
- Girl on top: Women lead deep changes and increase initiative.
- Doggy style: Depth is easy to reach, but you need to be careful with the angle.
Reason: Different body positions magnify the S-shaped effect. Data show that people who use multiple body positions have a high satisfaction rate.
Assistive tools
Use a vibrator or pillow to adjust the angle. Reason: To enhance stimulation, suitable for those with insufficient physical strength.
Why is it suitable for calling prostitutes?
EnjoyingCalling ChickenDuring a service, which is typically limited in duration (usually 15-30 minutes), prostitutes often need to adapt quickly to different clients. The advantage of S-shaped thrusting lies in its efficiency: it eliminates the need for complex positions; simply varying the thrusts can enhance satisfaction. When clients use curved techniques, prostitutes are more likely to experience genuine physiological reactions, rather than simply performing. This not only improves the quality of service but also avoids awkwardness for both parties.
on the other hand,Calling ChickenServices are often short-term, conducted in unfamiliar environments, with no emotional connection between the parties. Prostitutes are expected to quickly "get into the act," but achieving a true orgasm is difficult (case 10-20% only). S-shaped thrusting can be effective without prolonged foreplay.
Practical steps: How to implement
- Preparation: Use lubricant and choose missionary position (man on top, woman on bottom), with the woman's legs bent for easier angle adjustment.
- Start S-type: When entering shallowly, the head of the penis should be shaken left and right (S curve upward) at a slow speed.
- Accelerate to deepen: Move the middle part sideways to rub the G-spot and observe the woman's reaction (such as moaning or contraction).
- Climax Guide: Deep full S-motion, combined with hand stimulation of the clitoris. Continue for 5-10 minutes.
- Finish: Decelerate to avoid abruptness.
The mechanism and techniques of female orgasm
The female orgasm is divided intoclitorisS-type (external stimulation), vaginal (internal thrusting) and mixed types. S-type mainly promotes vaginal orgasms and involves pelvic muscle spasms and hormone release (oxytocin). Prostitutes have a low rate of orgasm (due to psychological numbness), but the S-type can be a breakthrough: multiple points of stimulation, building up to a critical point of pleasure.
Tips to help a prostitute orgasm
- Foreplay Combination: Warm up your body with finger or oral sex before the S-shape. Experts recommend "hand sex": gently stroke the clitoris to simulate an S-shape.
- Posture Optimization: Female supremacy, allowing the whore to control the depth of the S.
- Psychological guidanceCompliments and communication, e.g., "You're so wet, I can feel you getting there." Reduce stress.
- Extension Method: Nine shallow and one deep variant, blending into an S-shape.
- Aftercare: Post-orgasmic cuddling to enhance the emotional connection.
Analysis of the benefits of S-type thrusting
The benefits of S-Pumping are multidimensional, not just physical, but also psychological and relational. The following is a layered description, combining scientific data and experience.
Physiological benefits: Increased orgasm probability and duration
First of all, the most obvious benefit is that it helps women reach orgasm. According to Time Magazine, the rate of female orgasm is only 30-40% with traditional thrusting, but with curved techniques such as the S-Shape, it can go up to 60-70%. The reason for this is that the S-Shape stimulates the G-Spot and the A-Spot in a precise way, which triggers the contraction of the vaginal walls and the phenomenon of ejaculation (female ejaculation).
For men, the S-shape reduces linear friction and prolongs ejaculation. Studies have shown that the average time of penetration is extended from 5-7 minutes to 10-15 minutes, reducing the risk of premature ejaculation. In a cock-calling scenario, this means that the client gets "value for money" and the sex worker is less likely to be frustrated by "quickies".
In addition, the S-shape promotes blood circulation and strengthens the pelvic floor muscles. Long-term practice can improve erectile function and reduce the incidence of impotence by 5-10%. For sex workers, this helps to maintain occupational endurance and avoid chronic fatigue.
Psychological benefits: Increased intimacy and satisfaction
Sex is not only physical, but also psychological, and the variation of S-shaped thrusting avoids monotony and creates a sense of "exploration" that makes both partners feel valued. Psychological studies have shown that this technique can increase partner satisfaction 25% and reduce the feeling of "routine".
In hooting, sex workers often have to fake orgasms to please their clients, but the S-shape triggers a real reaction and reduces the pressure of performing. According to sex workers, numbness is the norm (nerve fatigue due to repetitive intercourse), but curved movements such as the S-shape can awaken sensitivity and allow them to enjoy real orgasms.
In the long run, S-type exercises cardiorespiratory function and muscle, equivalent to low-intensity aerobic exercise. Studies have shown that regular sex reduces the stress hormone 20% and improves sleep. For sex workers, this helps to cope with the high pressure of life.
in conclusion
The S-Style of sexual thrusting provides comprehensive physiological and psychological benefits through variations in depth and time periods. Chart data proves its effectiveness due to the variety of stimuli and rhythmic optimization. In practice, communication and safety are emphasized, and the process is enjoyable. Sex is an art, and the S-shape makes it perfect.
