I'm 16 years old, and recently got a girlfriend. We were at the movies the other day, and we were kissing, and I had an erection. After the movie, my testicles were in terrible pain, I was feeling nauseous, and at one point almost passed out. This also happened a week later, at another movie. On both occassions I recovered the day after and everything was back to normal. I think it is possible that due to the erection, my testicles may have been tightly squeezed against the theater chair, giving me what most of us would see as a normal reaction to getting hit hard in the balls. But from what i've read online, i'm also worried this may be testicular torsion, which lowers sperm count. I'll have a doctor look at it if necessary, but needless to say, i'd rather not. I didn't notice any swelling in either of the testicles on both events, but they did hurt terribly when I tried to touch them. Any ideas?
