I was wondering too whether you were asexual. On this really great forum for asexuals (AVEN- http://www.asexuality.org/en/
) they say that a med change, sexual abuse, change in weight... and other things can change ones sexual desire. That isn't asexuality. Asexuality is an orientation. Have you always had a lack of interest in sex? Or is this a recent discovery...? If you can't remember ever being interested in sex, then perhaps you are asexual. If you have been interested in the past and aren't any more then I would wonder what happened that changed that for you. It's fine that you are not into sex, but if it concerns you then maybe it would be beneficial to find out at what moment you stopped wanting it.
