On a recent night out I was kissing (french) - 2/3 times for 5 seconds or so, a girl who later turned out to be a stripper. I am now paranoid that I could contract a STD/I through the interaction. I was partially intoxicated and did not realise I had my corner of my lips sore from possibly "Angular Cheilitis" from a quick google search. I had it a few times and didn't think anything of it, it goes away by itself after a few days. Since the skin is slightly "cracked" but isn't deep, I think I am fine but cannot help being paranoid!
I also have never had sex so didn't think a std check up was necessary!
Help and advise on this matter would be much appreciated!
