Am I experiencing testicular torsion with my right testicle?

[devsterl]

I've been going on dates with a girl, we hadn't done anything sexual yet as it was the start of the relationship. However, simply holding hands got me aroused. No one noticed as much jacket hangs quite low and I was wearing jeans. However, I would stay erect for hours from constantly being aroused. Only after my date today, did I get pain in my right side (around where the appendix is) and behind my right testicle. It doesn't hurt when I pee, and I haven't ejaculated today (not sure if there would be more pain or not from ejaculation as a result). I don't think it's testicular torsion. The testicle seems to sitting fine, it's not higher or lower or anything. It's the same size. No swelling. The veins to right of right testicle do look dark purple though. It doesn't hurt THAT much, but there is some discomfort. I have had it before from roughly the same circumstances (staying erect for a long period of time, or from rough sex). But it always on my right side and the same place behind the testicle.

It maybe when I had. Epididymitis. Infection in the testicle tubes that carry sperm. I'm on antibiotics for it. Just finished today.

If it was testicle torsion. It'd be an emergency. As it cuts off blood to your testicle.
