it's certainly something to discuss with your gyn.
no, no sudden std symtoms like this occur.
There is but it involves taking a sample of your partners semen in, and having them create some sort of scratch test... kind of involved. I'm not sure who even provides this test. I can't visit a practitioner while symptoms are present because they go away in such a short time, which is what has me worried. Any time I self diagnose I obsess over it. In the mean time, condoms take care of them problem, I just wanted to know if there was some "instant onset STD" situation that could have similar repeat symptoms.
the best thing to do is to follow up with your provider for this. I'm not sure of the testing involved but I'm sure there is something they can do to check for this.
Until you figure out what is going on, best to only have protected sex from the sounds of things.

sorry forgot to clarify what I mean by "getting worse", this has only happened about 5 times total, and it's been over the 6 months we've been dating, sometimes when the timing is safe he doesn't pull out. I have no symptoms in between and it happens EVERY time he doesnt pull out, and never happens when we use a condom
