I've just ended a very long and drawn out, mainly sex based, relationship. Basically realised it was going nowhere and 4 years of good sex and bad conversation was enough. However my sex drive has dropped off the radar, vanished. I used to have lots of sex and masturbate on top of that, now I don't even feel like masturbating, or really having sex. I don't know whether to get worried or not, I mean SURELY it must come back at some point? I mean i'm only 22. Has this ever happened to anyone else ???
