How do i get rid of performance anxiety?

Hi guys, girls.

I've been having a problem for a couple of years now. I've read guides on the internet, old posts on /sex, those haven't helped much so I decided to make my own.

I'm a 26 year old male and I have a problem with getting an erection, this is definitely a mental issue. I've slept with five women and I've had problems with all of those women, but this is only during the first weeks/months of dating. With my last girlfriend we couldn't have sex for the first couple of months because I was just unable to get an erection during foreplay. Then just suddenly it works, I have no idea why. And after that it's not a issue (With those certain women)

This is really starting to get on my nerves and to a point where I've stopped dating women when it gets close to having sex with them, because I'm unable to handle going through this pain, this embarrassment. I have tried relaxing my mind, just enjoying the moment, done long foreplays. Right now I've started talking to a beautiful girl and I'm close to cutting it off, because of this.

I consider myself quite handsome, I work out, I'm in great shape and I don't have a problem talking with women and spend a lot of time with them. I've tried alcohol but when we arrive in the bedroom I just sober up and start getting nervous again.

I'm on the verge of thinking about seeing a shrink, but I really don't have the money for it. I've also thought about using some pills, but in my country they are by prescription only and I'm not sure doctors sign those off when it's only a mental issue. I also might think that it would only be solving the problem for a certain time. But maybe that's just what I need, a kickstart.

So I come to you, my experts. What do you think I should I do?
