"My nuts ached so bad I actually went the er only to be told it was a simple case of blue balls. The doctor told me to go home and jack off and don't wait so long between ejaculations. I like to edge because it gives me better orgasms. Is there a way to do that without my nuts aching?"
Blue Balls, or Epidydimal Hypertension, is a build-up of blood in the testicles caused by long periods of arousal without having an orgasm. It causes the balls to ache and a blue tint. Thus the name. According to the article "Edging: Definition, Benefits, and More" at Medical News Today:
"Edging is unlikely to have harmful side effects and will not cause any ejaculation problems. Edging rarely leads to epididymal hypertension, or 'blue balls.'"
It could be that you're causing slight testicular trauma by stroking so vigorously that your balls get bounced around and jostled a bit too much. Slow down the pounding a bit.
"Edging involves sexual stimulation and stopping just before the point of orgasm. Edging aims to extend a person’s sexual enjoyment for longer periods. It may also intensify the experience. It is possible to perform edging alone or with others. Anyone might engage in edging, regardless of their gender identity or sexual orientation. It involves stimulation to the point, or edge, of orgasm. People will stop just before the edge and take a small break from stimulation. Edging can involve repeating this cycle several times. Both males and females might use edging as a way to avoid premature ejaculation."
