I stopped PMO but now I'm incapable of sex

So I've only really stopped watching porn and everything as I felt it wasn't healthy, and previously before I did I had no problem getting it on, sometimes it was a bit too easy.

So I've stopped for the past 3 weeks, and before that for a good few months I've probably watched porn maybe once or twice in a fortnight, but I haven't had sex in about a year. Now I met a beautiful girl the other week, we jump into bed and I find I'm completely uninterested, literally like I was looking at a potato and not a nice woman. She tried a few things, unsuccessfully, and then goes oh yeah no problem whatever.

Yeah, whatever.

So not only does it make me feel completely useless, it's probably going to make this happen again due to the mental block. I feel like she's going to loose interest after that too, although somehow I doubt it was sex she was after in the first place as I'm ugly as hell, which if I think about it probably doesn't help because I don't feel attractive to her at all, if people say someone's out of their league, I'd say we're not even playing the same sport, this girl is stunning.


Is this a normal problem? I expected it to be like a pocket rocket and go off in seconds, instead I wasted like 20-30 minutes feeling like a fool. My sex drive is definitely less than what it used to be, I almost never get random erections now nor look at women and get distracted, is this healthy for a 20 year old male? The only thing is for the last week I've been absolutely exhausted as I've been going out a lot and my personal life is pretty hectic and stressful, but somehow I doubt that's what's making the difference with a girl like this.

If I masturbating and watch porn a few times is what fixes this then that's fine, I know myself that now that I've stopped so long I can do it for a week straight then just stop, I've done it a few times over the last year when I'd go out and get wasted at the weekend and not really care, but I still feel bad about it so would prefer avoid that if at all possible.
I'd try imagining the same girl and doing it but I can't hold an image or a thought for that long before it changes into something horrible, so I'd have to use porn.

 

Reading about it on your brain on porn makes it sound like it's going to last for a while, I recon this girl will have lost interest by that point, fantastic.

I've been going in and out of this no libido for a while now, sounds like it's only really made the situation worse, it's a shame this isn't more generally known or talked about outside of communities like this.

 

She's foreign on an exchange program from another continent for a few months so I won't see her for very long, not to mention her English isn't the greatest so it's kind of hard to explain things, be even harder to explain this, I can barely even make a joke understandable at times.

As for her feeling bad I never really thought about it that way, maybe it would be worth saying something, I don't know. It's literally the most annoying thing to happen at the worst time, I barely even have a want for this girl although I can see she is attractive.

 

As shallow as it comes across there isn't really that much of a point, to reiterate she is only going to be in the same continent as me for 9 more weeks. If she was here to stay I totally would but she's not so that would only really end up hurting people 9 weeks down the line, and let's be serious who could keep up a long distance relationship over the other side of the world with two people both so poor they could never see each other again.
I'm not saying I have zero attachment, I like her but we're not really going to be doing anything beyond those 9 weeks.

Edit: should probably also add we have spoken about it
