I am 26yrs old guy, I did sex two times with my girlfriend during her menstrual period, she wanted alot at that period, Now my penis has become weak since! could that be the reason why my penis has become weak during sex intercourse?
Well I cow
D be but there is pills u can take to make ur penis bigger and less weak I don't know what they r called tho
but can that be the reason or something else?
No, sex during a woman's period will have no effect on your penis.
