When I won the golden gloves I was told not to have sex the night before. I was 15 and a virgin lol. Its a myth and psychological. There is no scientific proof of its validity and its all in the head (no pun intended)

It only has an effect if you believe it to be fact. A kind of sincere delusion.
Lots of greats have believed it and lots have not. Hagler would include celibacy as part of his training weeks before a fight and Leonard would be shagging chicks the night before a fight.
I wont even attempt to answer for a female. I will instead accept what Missy has to say on the matter since she is a women and a boxing fan. Women are far more complex then we neanderthals.
