I have heard that us guys tend to taste different depending on what we eat (like pineapple making it taste sweet) but in my experience, the only factor in the taste of a woman is hormonal changes as you approach menstruation. A woman will taste different at different times of the month.

Yeah, I have heard that for both men and women, but I don't believe it either way. Just me though. Onions, garlic and strong things like that I think affect body odor, breath and such, but as far as changing the taste of your "fluids" I don't really think so.
It may work for men, I really don't know as I have never/would never taste cum, but I don't think it works for women.

I can tell when my husband has been eating too much junk food! :p so,it would make sense that women can be affected also.Patty
