i guess the problem i'm having is blue balls, pain in the testicles after an erection with no ejaculation. but the pain is very extreme and it lasts for several hours afterwards, even when i have no erection. do i need to see a doctor?
Nope, blue balls are the result of blood flowing into your scrotum and penis during arousal. Since there was no ejaculation you'll experience some pain/discomfort there and it isn't uncommon for it to last that long. Masturbation to ejaculation will cure it every time....absolutely no need to see a doc on this one.
