A week ago I had unprotected sex with a partner who I thought was clean, I know that I am. But recently I have been experiencing itching of my labia but have looked and don't see anything out of the ordinary. But when I looked a little deeper, I thought my urethral orifice seemed swollen but I don't normally look so I'm not completely sure. Could this be something or am I freaking myself out?

This happened to me. Ichying may happen with any infection or anything unclean it swells from the ichying there are so many nerves inside that can rip if you scratch so hard to break it open. It's really nothing to freak or worry about for that matter. I would say if it doesn't stop get it checked out just to make sure and the only std it would possibly be is hvp which is extremely common and is easily taken care of by antibotics.

It can be itching for many reasons, normally an infection of some sort but could also be an STD. time to get checked to be sure
