No, it is common in most men who get random erections (erections that occur when there is no sexual physical or mental stimulation) or men who have prolonged sex with no ejaculation.
It's a myth. I used to use it as blackmail so that my girl wouldn't tease me about sex, and she would follow through with it. But men don't ever actually get sore down there from "blue balls."
well its more of a trauma or infection symptom
No you should not. All men will have blue balls at some point in their life, and it is a relatively common thing, so you have no cause for alarm. Unless your testicles turn blue. THEN you should rush to the hospital (not emergency room; that could take HOURS) and get it checked out as quickly as possible.
hairy testicles
No.
kick them in the balls
they have it because its awsome XD
only when you touch them
With a razor! CAREFULLY!
The balls are inserted into the rectum (lubricant will be necessary). Their movement stimulates the prostate, which can trigger an erection in most men.
Approx 3.8 billion men in the world so that makes 7.6 billion balls
no my man it comes from the male testes, a.k.a. "balls".... Wow what you thought buddy ol' pal was really twisted ha
