Hey,

I'm a guy.

On Saturday I received oral sex from a guy I had met for two minutes, but I stopped him because I just generally felt uncomfortable with the situation (it was consensual). However, since Sunday or Monday I noticed that my penis kept having this on and off tingling.

Today (tuesday night), I noticed the left part of the top my urethra looked a little bigger and maybe a little redder. It didn't look like a bump, but it could have been. After the shower, I noticed it had gotten smaller and soon realized it had drained. Now I'm a bit worried that I may have something

Could this be herpes

or an irritation from using soap to clean my penis after the oral?
