What are some sexual positions where the woman is on top and the man is on the bottom? Why is it so pleasurable?

女子在上,男子在下性愛姿勢怎樣玩-為什麼這麼爽

(Crab Position I) is the ultimate female-on-top variation where the woman is completely dominant and the man lies completely flat and enjoys the experience. The woman leans back in a "crab crawl" position, with her hands supporting her on the bed and her feet firmly planted on the ground. Her penis is deeply enveloped and precisely positioned to reach the G-spot, satisfying visual, tactile, and control sensations all at once. Many couples become addicted after trying it once because it's so pleasurable it makes their legs go weak.


What exactly is Crab I's pose? And why is it called "crab"?

The man lies flat on the bed with his legs naturally slightly apart or his knees slightly bent, serving as a backrest.
The woman straddles the man's waist, facing him, allowing his penis to fully penetrate.
Then the woman slowly lies back, stretching her arms straight back on the bed (or the man's thighs or knees), with her feet firmly on the bed, knees bent or one leg straight (as shown in the picture), her entire upper body arching backward.
At this moment, the two men's pelvises are pressed together, and the penis is "pressed down" due to the angle, with the head forcefully rubbing against the G-spot area on the front wall of the woman's vagina.
The woman's arms and legs support her body like crab legs, hence the name "Crab I".

The biggest difference between this pose and the standard cowgirl pose is:

  • The average cowgirl sits upright, but this is leaning back at a 45-70 degree angle.
  • The angle allows the penis to naturally curve and reach the G-spot, while the woman's clitoris can rub against the man's pubic bone.
  • Visually, the woman has a high, firm chest, her head tilted back, and a dreamy expression, while the man lies down and enjoys the entire scene, experiencing an extreme level of pleasure.

Why is Crab I so great?

1. The ultimate pleasure point for women (90%, women who have tried it say "I never knew the G-spot could be so obvious").

  • G-spot stimulation: The corpora cavernosa of the G-spot, located 2-5 cm from the anterior vaginal wall, is continuously struck by the glans penis at an upward angle. This angle is difficult to maintain in a normal position, but Crab I naturally locks it in place.
  • Double clitoral stimulation: During grinding, the clitoris is pressed directly against the man's pubic bone, moving up and down and grinding back and forth, stimulating both the glans and crura of the clitoris simultaneously.
  • The A-spot (anterior fornix) deep inside the vagina is also reached, making it easy to squirt or have multiple orgasms.
  • Sense of control: You have complete control over the depth, speed, and angle. The psychological pleasure of "I'm going to fuck him until he surrenders" will cause a dopamine rush, amplifying the pleasure by 3 times.

2. The ultimate pleasure point for men

  • Tight Envelopment: The woman leans back, causing her vagina to contract naturally, and the penis is "pressed down and squeezed tightly," resulting in strong friction on the frenulum and the coronal sulcus of the glans.
  • Visual bombardment: lying down and watching a woman's breasts sway, her waist twist, and her face contort with ecstasy is like watching a live sex show.
  • The contrast of being "ridden": Usually, the boy takes the initiative, but this time he is completely controlled by the girl, which gives him a strong sense of being conquered.
  • Enhanced endurance: The angle allows men to relax and enjoy the position without having to thrust too hard, and many people last more than 20 minutes in this position for the first time.

3. Shared enjoyment points

  • Intimacy: Although leaning back, eyes can still meet, and breaths and moans are directly transmitted.
  • Increased blood flow: When a woman leans back, blood rushes to her brain and genitals, increasing sensitivity.
  • Novelty: Challenging positions cause the brain to release more excitatory substances, making it easier to reach orgasm simultaneously.

Preparation before actual combat

  1. Environment: The bed should be soft enough but not sagging. It is recommended to place it in the center or at the foot of the bed (men should have their heads against the headboard, and women should have space for their feet to stand firmly).
  2. Foreplay should last at least 20-30 minutes: oral sex, fingers, nipples, neck, ears, etc., thoroughly explore and make the woman completely wet.
  3. Lubricant is essential: Even if she is very wet, and there is a lot of friction due to the backward tilt angle, it is recommended to apply water-based or silicone-based lubricant to the penis and vaginal opening.
  4. Condoms: If needed, put them on beforehand to avoid being flustered during intercourse.
  5. Two pillows: one to place under the man's buttocks (to increase the angle), and one to support the woman's lower back when she leans back (to reduce back pressure).

Step by step into Crab I

Step 1: The man lies flat on his back with his legs slightly apart at about 30 degrees, and his knees can be bent to support the woman's arms.
Step 2: The woman faces him, kneels on either side of his waist, first uses her hands to guide his penis, then slowly sits down and completely engulfs it.
Step 3: While still in the inserted position, the woman stretches her hands back, palms down, and supports herself on the bed (or the man's thighs).
Step 4: The woman slowly shifts her weight backward while moving her feet forward, placing her soles firmly on the bed.
Step 5: Adjust to the most comfortable angle – the penis should be pressed down slightly but without pain. The woman can try moving it up and down slightly to confirm that there is no discomfort.
Step 6: Let's begin! First, grind slowly for 5 minutes to allow both of you to adjust.

(If the man experiences pain due to penile curvature, he should stop immediately, move forward slightly, or switch to a regular female chauffeur.)

Complete Guide to Practical Gameplay

Basic gameplay (10-minute tutorial for beginners)

  • Bouncing up and down: Bend your knees and use your leg strength to move up and down. Each time, only rise until the glans is stuck at the entrance, then sit down heavily.
  • Grinding back and forth: The buttocks rock back and forth, like drawing an 8 on a man's pubic bone. The clitoris trembles with pleasure.

Advanced gameplay (so exhilarating you'll scream!)

  • Rotary grinding: After sitting all the way down, draw circles with your waist, and scrape the G-spot with your penis inside 360 degrees.
  • Single-leg straight version (completely imitates the picture): Extend one leg straight forward, bend the other leg, change the angle to stimulate different points.
  • Quick short thrust: only rises and falls 3-5 centimeters, high-speed vibration, specifically targeting the first half of the G-spot.
  • Man takes the initiative: The man holds the woman's buttocks with both hands and thrusts upwards forcefully, while the woman only needs to squeeze tightly.

Two-person teamwork skills

  • A man can use his thumb to press and circle a woman's clitoris.
  • A woman can support herself on the bed with one hand and rub her own nipple or a man's nipple with the other.
  • Eye contact: The woman leans back and deliberately looks down at the man, saying, "Watch how I do you."
  • Swearing adds to the excitement: "Your cock is going in so deep... I'm going to cum..."

Climax Sprint Phase
When the woman felt she was about to climax, the man switched to rapid, small-amplitude grinding while simultaneously thrusting upwards, causing her to moan loudly, and his fingers to rub her clitoris more quickly.
Many girls experience their first orgasm in this position because of the combined stimulation of the G-spot and clitoris, plus a sense of psychological dominance.

Variation

  1. Crab Reverse (back view): The woman turns around with her back to the man, leans back and supports herself with her hands, and the man's view becomes her buttocks and back, creating a deeper perspective.
  2. Male knee support version: The man raises his knees, and the woman supports her arms on her knees, reducing pressure on the woman's wrists and allowing her to play for longer.
  3. Bedside version: The man lies on the edge of the bed, while the woman stands with her feet on the floor. The height is just right, making it easy and deep.
  4. Pillow-elevated version: Men place two pillows under their buttocks, creating a more pronounced angle and doubling the stimulation of the G-spot.
  5. Combined with a vibrator: The woman holds a mini vibrating egg in one hand and presses it against her clitoris, while supporting herself on the bed with the other hand, resulting in a double orgasm.

Frequently Asked Questions and Solutions

Question 1: Male penile pain → Female should not sit too far back, and should keep the penis at approximately a 90-degree angle to the body.
Question 2: If a woman's wrists are sore, she can support herself on the man's knees, or the man can support the woman's waist with both hands to share the weight.
Question 3: Woman's legs shake and she can't stand → First, practice yoga "Crab Walk" to strengthen her core.
Question 4: Too deep insertion hurts → The woman controls the height of the insertion and only performs shallow insertion.
Question 5: Too tired to last long → Switch to regular cowgirl mode every 5 minutes to rest, then switch back to Crab.

Final summary and encouragement

Crab I isn't the easiest position, but it's definitely one of the most enjoyable.
It combines "female dominance + deep G-spot stimulation + visual enjoyment + psychological control" all in one package.
Many people laugh, scream, and feel weak in the legs the first time they try it, but the second time they actively ask, "I want crab style again tonight!"

Remember three core principles:

  1. Sufficient foreplay and adequate lubrication are essential.
  2. Communication is the most important thing. If you're in pain, speak up. If you're feeling good, shout it out loud.
  3. Safety first, enjoyment second.
