My girlfriend recently blurted out that we haven't slept together in a long time. This was during an argument we had.

One question I have is whether she really wants to sleep with me or whether she's wondering why I haven't slept with her. I guess I'm wondering how important sex is to her? I know it's a personal thing, but maybe if someone can tell me how often females need to do it.

Problem is that I have no libido at the moment. I went to the doctor and he said that it can't really be fixed, although he can give me Viagra if I want. But would that really fix my libido or would it just make me functional?

I'm in the 24-36 age bracket, and so is she.
