I'm wary of fucking with one's chemicals, especially mood altering ones, but hormonal ones too.

I considered going on the pill, because I have absolutely HORRIBLE periods (as in bedridden by cramps) and so that I could have an excuse to be on them if I wanted to be sexually active in college (ehem). BUT, decided against it currently, and from what you've said, someone with no sex drive to begin with prrrrobably shouldn't be on it. ;)
