When my ex was taking winny, she wanted to have sex 6 times a day. I am not sure why gear raises sex drive in women, but there is deffinitelly an increase going. When she was off winny she barelly wanted it once a day. It felt worsed than being married.
Dude women also produces testosterone. Of course in very low quantities compared to men. That's why we are thinking all day long in sex and watching every ass on the street and they don't. I mean, they look but with another "eyes"...y'know...we are more like animals. If a woman has her testosterone levels raised (with steroid for example) she will be horny like a horse. All depending in the doses of course.
What about just weight training affecting the libido, excluding steroids? I never took steroids but my libido has definitely been affected. Isn't this true for women who lift?
