Having a woman on top isn't quite the wild ride most men might have imagined.
Scientists have learned that the 'woman on top' or 'cowgirl' position is the most dangerous one for men to engage in during sexual intercourse.
According to new research, the risky position is to blame for half of all penile fractures that occur during sex. In comparison, 'doggy style' or the woman on all fours is responsible for 29per cent of injuries, while 'man on top' or 'missionary' is only liable for 21per cent.
In the study published in Advances in Urology, researchers hypothesized that a man is prohibited from quickly stopping a painful movements when a woman has her entire body weight on his erect penis.
However, if the man is in control, he has a better chance of minimizing injury by disengaging in harmful movements as soon as they happen.
Of the 44 suspected penile fractures studied in three hospitals in Campinas, Brazil over the course of 13 years, 42 cases were confirmed - and evaluated in order to discover what the initial cause was.
Twenty-eight of the men were having heterosexual intercourse during the time of injury, while six of the subjects were engaging in 'penile manipulation'.
Four were participating in homesexual intercourse, and it was deemed to be 'unclear' how the final four men had sustained their injuries.
Half of the patients who participated in the study heard a crack when they were first injured, followed by swelling and pain, while two of the men actually developed erectile dysfunction following the injury.
But before you swear off your favorite position remember that penile fractures are rare.
The researchers describe the injury as being a 'relatively uncommon clinical condition that frequently causes fear and embarrassment for the patient'.
Despite the awkward nature of the injury, men should seeks a professional opinion as soon as they feel pain.
According to the study, a delayed search for medical assistance following a penile fracture can 'lead to impairment of sexual and voiding functions'.
