To the point: I have no libido anymore. Nothing really changed, just one day it was gone.

I was with my ex girlfriend at the time when it happened and our relationship wasn't good anymore. We were having sex one day, she was on top, and I just felt like I didn't want her touching me anymore. After she left, I figured it was just because our relationship was basically over. I've never been one of those guys that can just have sex with anybody, there has to be something there and I figured I didn't want her anymore because I truthfully didn't even like her that much by that point.

So I broke up with her about a week after that day.

Then I realized my sex drive was pretty much gone for good. I'm in my late teens, aren't I supposed to be like crazy horny? I seriuosly used to have a healthy sex drive. I'd jerk off every other day or so (sometimes more, sometimes less depending), used to be into trying new things with my girlfriend, all that kind of stuff.

The way things are now, I barely even masturbate. I honestly can't remember the last time I did. I think it's been over a week now. When I do it, it's not because I'm actually horny, it's more of a physical thing like taking a dump - I just need to get rid of semen. I mean of course it feels good, but after that I never really have an urge to do it again until the next time I "need" to.

Nothing is wrong with me mentally or physically that I know about. I'm not depressed and please nobody post "It's cuz yer GAY lolz". I'm honestly not really sexually attracted to either sex anymore. There are some girls I think are hot, but I don't fantasize about them like I would have before, and if they asked me to have sex I know I wouldn't. I mean I suppose I could have something wrong I don't know about but if that were true, why would my sex drive just leave overnight? Nothing sexually traumatic has EVER happened to me, I wasn't abused, my parents are cool about things like that, nothing awful even happened with my ex, we just weren't right for each other.

I suppose it's good in a way, like how many guys are gagging for sex that can't get any? I don't know if I could or couldn't, I pretty much don't even try. I'm not interested. At all. I do see it as a problem, because I didn't plan on spending the rest of my life alone, and no girl is going to want to be with a totally sexless guy. Also my lack of sexual feelings is stopping me from pursuing relationships - why chase girls when you don't want sex?

Has this ever happened to anyone else? What should I do? BTW I already did ask my doctor about it and he said "you're probably just stressed" because I did just move for college and yeah I am a little stressed but not THAT much if you know what I mean. And this happened to me in while I was still in high school so I really know that's not it.
