Hi everyone, two days ago I had protected sex with a girl however the oral was uncovered. Yesterday, my penis started to tingle. It's hard to describe as it doesn't really hurt but it's really annoying. It just tingles at random times. Everything seems normal, it doesn't hurt when I urinate or when I masturbate so I really don't know what the problem is. I've only had it for two days so I'll see if it goes away in a week's time. I'm just worried that it could be a STD, but I've done some research online and someone said that it could be a problem with a nerve and I've read somewhere that just having a tingling penis isn't a symptom of a STD although I'm not really sure.

Can anyone help me?
