After my boyfriend and I have unprotected sex, I always go to the bathroom after just as a precaution. But when I urinate my vagina (the outer part) burns like hell. It is also swollen and sore to the touch. We are both 18 and have been recently tested, we're both clean. He has no complaints of discomfort or anything.
I am clueless on what to do or who to go to.
Any information will help, thanks.

I had the same problem but for me it was because I barely started having sex. The vagina isn't used to being so roughed up you know ? Lol. Idk after about a few more times it stopped burning. It still sometimes gets a little swollen but it's less and less over time. (I am 20years old btw) :)

If this happens within hours of having sex, then it is probable that you needed some lubrication (KY jelly or astrolube) or some time in between events. If it keeps on happening talk to your doctor.
