I'm 18 years old and sexually active with my boyfriend of six months, now. A few days ago he complained of feeling as though he had to pee, but couldn't & said it burned a little. Three or so days later it started burning just a little when I used the restroom. The next morning, I woke up and when I peed, it burned really bad. Bad enough to make me cry. It smells down there: not like fish or anything. Just a really weird odor. And there's a little blood in my urine when I wipe. What could this be? Please and thank you!
