How a man's penis got so big

No, no, it wasn't caused by any of the modern marvels to counter erectile dysfunction, it was biological evolution ensuring good sex and the consequences thereof, says Dr Bowman. A report at Press Esc:

"As the diameter of the bony pelvis increased over time to permit passage of an infant with a larger cranium, the size of the vaginal canal necessarily also became larger, potentially resulting in a vaginal-penile discrepancy in size," Dr. Bowman pointed out. "Sexually satisfying coitus requires a satisfactory 'fit' for both partners."

This meant that as humans evolved, men with larger penises fared better through natural selection as they had a better change of having satisfying sexual intercourse and ejaculating, causing more women to become pregnant.

If I had more time, perhaps I could dig out the book(?)/article(?) from which I gleaned the factoid that penile size in mammals is directly proportional with the amount of force/coercion typically used during sex.

Just think how hung human males would have to be to accommodate their partners if the pelvis and birth canal were sized to allow safe & easy childbirth...
