The position most prone to penile fracture in men

Woman on top with her back to man (that is)Reverse CowgirlThe woman fiercely scraped him up and down.Rupture of the tunica albuginea of the penis (commonly known as penile fracture)One of the high-risk positions, often listed as the "most dangerous" or "most prone to breakage" position. Many people hear a "snap" sound, and their penis instantly goes soft and swells into a purplish-black eggplant shape.

Penile fracture(Penile Fracture) refers to the fracture of the penis outside the corpora cavernosa due to a violent impact or improper bending during erection.White membrane"Tearing and rupture often occur during sexual intercourse (especially woman-on-top) or rough masturbation. Symptoms include a 'pop' sound, sudden sharp pain that subsides quickly, and swelling and bruising resembling an eggplant. This is a urological emergency; if the tunica albuginea is not surgically repaired promptly, it may lead to permanent erectile dysfunction or penile curvature."

Key response principle: Seek immediate medical attention; do not apply heat.

Penile fractureKey knowledge

• Etiology: Although the penis has no bones, the tunica albuginea thins out during erection. If it is hit against the pubic bone or subjected to strong bending, the tunica albuginea (like the outer membrane of a balloon) can rupture, causing bleeding in the corpora cavernosa.
• symptom:
  • I heard a "snap" sound during intercourse.
  • Severe pain.
  • The penis instantly went limp.
  • The penis rapidly changed color and swelled into a purple (eggplant-like) shape.
  • Approximately 10-221 people with TP3T may also experience urethral injury, resulting in hematuria or difficulty urinating.
• Treatment and prevention:
  • Emergency requiring surgery: In principle, surgery to repair the tunica albuginea should be performed within 8 hours. If treatment is delayed, the risk of sexual dysfunction sequelae will increase significantly.
  • Emergency measures: Apply a cold compress immediately, do not apply heat, and go to the emergency room immediately.
  • prevention: Avoid vigorous or excessively contorted sexual positions. For example, be extra careful when the woman is on top of the man. If any abnormalities occur during sexual intercourse, stop immediately. 

If you encounter a similar situation, do not delay due to embarrassment; seek medical treatment immediately to reduce the risk of long-term effects.

What is a "penile fracture"? Why does it hurt so much even when it's not a real fracture?

penis itselfNo bonesThe so-called "fracture" is actuallyThe white membrane (tunica albuginea) ruptures.

The tunica albuginea is a tough fibrous tissue that covers the outer layer of the corpora cavernosa of the penis. It is both elastic and strong, and its main function is to maintain the rigidity and shape of the penis during erection. When erect, the tunica albuginea compresses the veins to prevent backflow of blood, keeping the penis engorged with blood.

• When the penis is erect, it becomes hard due to the engorgement of blood in the three corpora cavernosa (two penile corpora cavernosa and one urethral sponge).
• It is covered by a tough white membrane, like the skin of a balloon, which thins to only 0.25–0.5 mm when erect.
• If you haveSudden forceful bending, impact, or excessive stretchingThe tunica albuginea tears with a "snap," and blood leaks out of the corpora cavernosa instantly → the penis immediately goes soft, swells, and turns purplish-black (a typical "eggplant deformity"), accompanied by severe pain.
• Common complications include urethral injury (hematuria, difficulty urinating) and bilateral rupture of the corpus cavernosum (more serious).

Why is it most dangerous for a woman to be on top with her back to you and then violently thrust up and down?

The risk of this posture comes fromFour Deadly MovesOverlay:

• The woman is completely in control + blind spotsThe woman is facing away from the man, so she cannot see the angle of his penis entering and exiting. The man can only see her buttocks from behind and cannot adjust or stop the penis in time.
  When the woman becomes aroused and vigorously thrusts up and down (forceful, fast, and deep), the penis easily...Slipped out of the vagina(Especially when the angle is slightly off, lubrication is insufficient, or the rhythm is out of sync).
  After sliding out, the woman continues to sit down → her full weight (50–70 kg+) presses directly on the erect penis, the penis is bent at more than 90 degrees by the pubic bone or pelvis, or even bent backward → the tunica albuginea tears instantly.
• Most unfavorable angle + greatest bending force:
  When facing away from each other, the angle of penile insertion is already higher (pointing upwards), which can easily cause discomfort when the woman moves up or down.Unnatural bending(Especially when pressing down or rocking back and forth).
  When the woman is on top (face-to-face), they can synchronize their actions through eye contact or kissing; but when they are facing away from each other and completely blind, the risk of losing control is much higher.
  A violent shoveling motion (siting down hard and then pulling up hard) will produce...Instantaneous high impactIt is more than 10 times more dangerous than slow grinding or rocking back and forth.
• Gravity + Body Weight Total PressureWhen the woman is on top, all her weight is concentrated at the base of the penis. The man, lying flat, has no leverage or way to avoid it, and if he slips off, it's like being crushed by a mountain.
  Doctors often describe it as: "The clips weren't aligned properly, so it broke."
• Excitement amplifies risksThe more pleasure the woman experiences, the harder she thrusts; the harder the man becomes, the more fragile the hymen becomes (the thinner the hymen). Many men accelerate their thrusts before orgasm, which is precisely the peak period for rupture.

Real-world cases and aftereffects

• Common scenarios: Qixi Festival/Christmas/holiday passion, car sex/bathroom/small space, drunkenness or infidelity (high excitement, poor control).
• Symptoms: A snapping sound (like a corn stalk breaking), severe pain, loss of erection, swelling and dark purple discoloration of the penis, and bending and deformation.
• Sequelae (if treatment is delayed):
• Penile curvature (>30 degrees, unable to insert).
• Erectile dysfunction (ED).
• The length has shortened (fibrillation).
• Psychological trauma (fear of sex).
• Fortunately, the surgery was performed within 24 hours, and the patient recovered to normal with a TP3T level of 901 (the tunica albuginea and corpus cavernosum were sutured).

How to avoid

It's not that you can't play, but...Play smart:

1. Slow startStart by slowly grinding or rocking back and forth to establish a rhythm. Don't start with aggressive up-and-down movements.
2. Hand-assisted aimingThe woman should hold the base of the penis with one hand to ensure it is aligned each time she sits down. The man can also support the woman's hips to guide her.
3. Reduce heightThe woman should bend her knees more (avoid standing or sitting with straight legs) to reduce the impact of the fall. Alternatively, the man can slightly bend his knees to help with the weight.
4. Communication FirstIf the man feels the angle is awkward or it hurts, he should immediately stop. If the woman feels she has slipped out, she should also stop immediately.
5. Variations in gameplay: Change to the woman leaning forward (with her hands supporting the man's legs), making the angle gentler; or add a pillow to support the man's buttocks, making the angle of the penis safer.
6. Sufficient lubricationDryness makes it most prone to slipping.
7. If you want intensity: Correct the position so that the woman is on top (face-to-face), with eye contact synchronized, and the man can adjust in real time.

Sex should be comfortable and safe for both partners; don't let a moment of impulse ruin your future.
