Sorry for the delayed response mate. Feeling sorry for myself with flu.
I'd agree about the gay clubs, in that many do want to sleep around etc, but as already mentioned, that's pretty much the same with straight clubs, although possibly not so immediately apparent.
There are so many other places to meet people though. My circle of gay friends is small, but the ones I do have are the ones I've selected and feel comfortable with. I actually found Tinder and Gaydar really useful by being strict with my filters, making it clear I want friendship and chat first, and I've built from there. It's the taking it further that troubles me, but that's down to my own issues. Another great place as you're a football fan is an LGBT footy team. We've got Cardiff Dragons down my way and I'm 99% sure there's a Liverpool-based one if you're from around Merseyside? (Edit: here it is-

Is it the fact that you've slept around after drinking that makes you feel dirty/ disgusted? If it's more personal issues that make you feel uncomfortable etc then I'd recommend asking your GP perhaps for Psychosexual therapy. It's incredibly useful for some people- doesn't make you feel uncomfortable but works through past experiences, employing CBT and relaxation techniques to make you feel more comfortable and certain. Also as mentioned CBT can help with making those irrational thoughts more logical.
Honestly feel free to PM me/ add me as just extending your friendship group is such a massive support when dealing with this as it evidently sounds as if you're talking your own mind in catastrophising things. Share your problems with people you feel you can- and if there aren't enough people you feel you can do that with, try just finding one or two out there. You'd be really surprised with how many others are going through really similar troubles. Again, there if you need a chat bud
