I had sex for the first time about six months ago, and for about a week following it, I was incredibly itchy. It went away, but a few months ago I started getting itchy again. It usually happens around the time when I have my period, and it's happened for my past few periods. My lips get red and dry and I was also getting a kind of smelly discharge, but it wasn't chunky. It always goes away though, so every time I try to go to the doctors about it, it's gone by the time I get around to making an appointment. I had sex yesterday, and afterwards everything down there was just SO dry. When I went to the bathroom a few hours later, my lips were bleeding, and today they're all cracked and chapped and dry and peeling. Has anyone ever heard of anything like this before? I'm thinking it's an STD, but my doctor said it may be a side effect of the medicine I was taking. What do you think?
