Hi, last week I spent a week with my boyfriend (we're both 21) . We had loads of sex. Now, a couple days later I have to pee all the time, my vagina hurts, I'm pretty sure it's swollen and it's pretty red. I also have this odor that kind of smells like dried period blood? I am on birth control & I'm not getting my period for another two weeks. What do you think it is/what should I do? By the way, I've had sex with another man besides my current boyfriend.
