So about a week ago I noticed that it hurt when I pee, during sex, but also just in general (though that as much as when I peed or had sex) so I went to the doctors and got prescribed antibiotics for what they thought was a possible UTI. 

I'm still on the antibiotics (smz/tmp ds) and it doesn't hurt to urinate anymore. However, I realized there is occasionally still some dull pain and it's from my clitoris. Looked down there and there is some white stuff around my clitoris, which comes back the next day after I wash it. Tried having sex again a couple times and it also still hurts despite my boyfriend trying to be gentle as possible. Feels like I can't get as wet as usual. 

Vaginal discard seems normal. I'm 18 and only had one sexual partner and my boyfriend got tested before we were sexually active and he is clean. I also wash down there every night with just water (have been doing that since almost forever). 

Would be nice to get some insight on what it might be and if I should go to the doctor again.
