Pain

@Norway1987 Ouch! it sounds like you have a good case of "blue-balls" (also known as vasocongestion). I get them too. A delicate question for you: when did you last ejaculate? If you become very sexually aroused and do not ejaculate often enough, that can bring-on the achy feeling. You can try some "home remedies" like cold compresses or just waiting-it-out. But for me, just a good-old wanking will relieve the pain almost immediately. Are you practicing semen retention? You may have to "time" your ejaculations to minimize or eliminate the blue-balls. Good luck!

Yeah, I think I just have to keep wanking :p
It's less than three days since last time, but I've been arousing myself with the hypnaerosession and some porn the recent days as a load up to the session with my helix today. Irony is that I think that's what ruined the whole thing today

I have found that I have the deepest most pleasurable orgasms if I do them within 12 hours after ejaculation. For me .... having a congested prostate restricts its ability to expand and contract in anal induced MMO orgasmic spasms.

Maybe that's the case for me as well.. Gonna try a new session tomorrow!
