What is going on ??

[Englishmajor1]

So, I hooked up with this guy about two to three weeks ago. I met him on a Thursday we hooked up on a Saturday and then we hooked up again the following weekend after that too. Im a Virgin and still am. We did everything but penetration. He did however rub the his tip against my vagina. He didn't cum, I sure of that. Just about a day and a half ago my right labia started itching. Now my left one is already enlarged. It got enlarged randomly my underclassmen years of high school. Before it enlarged it got REALLY itchy. So, back to my current problem my right labia is itchy and slightly red. I have been itching so that's probably the main reason it's red. I haven't noticed any abnormal discharge. I haven't gotten my period yet, but I can feel is coming because I just know how my body is. My question is does this sound like a STD to any of you guys. This was my first legit hookup and it would be unfortunate if I caught something.
