#std?

what the fuck is that

I knew Thursday night was a damn mistake.  Wasn't bad enough that the sex with Taco boy aka Thursday boy was bad... but I told him before we started that he would have to wear a condom... he appeared to put one on but I realized when it was over that he hadn't.  Suddenly I have this errr... umm...place.. kind of like a small red bump down there.  Its on my perineum or whatever you call that... it itches a bit and it slightly hurts and its close to the area that gets a lot of friction during sex.  I can't decide whether to worry or not... but of course I am worrying.  I've never had a STD and I sure as hell don't want to start now... I'm not sure if its just been irritated by my choice of underwear or if its more.  And I'm not sure how long I should wait.  I managed to get a mirror and see it (and its not an area of my body I like to look at either) and its not gross looking or anything like the pictures I saw online for all of the STD's... Any suggestions??
