According to a recent study, the sex position most likely to cause injury is the Cowgirl position.
Researchers
found that penile fractures were 50% more likely to happen when
partners were in that position. The Cowgirl is a sex move where she
mounts the man, her on top, straddling him. Doctors and academics looked at patients attending three A&E units with suspected "penile fractures" over a 13 year period. Half of them reported hearing a crack before experiencing pain, with some also suffering swelling.
The injury will most likely happen if she is in the position, and leans back.
Like
an elbow or knee, your erect penis can be “hyperextended” if you put
too much or too frequent downward pressure on the shaft. Over time, this
hyperextension can lead to peyronie’s disease, a
buildup of plaques that causes your rod to bend while erect. That can
make sex impossible. If you feel tugging - or even a small joint-like
crack near the base of your penis, the angle of your intercourse is a
little too extreme. Have her lean forward. A better move? Try reverse cowgirl, where she faces your feet.
