I've been learning about edging through Artistry of Male Blogspot and enjoying at least 20 minutes a day for several weeks, choosing not to ejaculate. If I expand the time, will this lead to "blue balls?"

Possibly at 2 hours. They are not that bad, is only a matter of expecting them and see them as a sign of good edging.

Thanks, that's helpful. Do you know of any medical articles which take a positive view of edging? Have you ever edged for very long periods of time? What are some of the positive effects edging has had for you?

I believe it's actually bad for you. Burns up HPT axis as well as neurochemicals like dopamine. Also cause prostaglandin-2 build up in penis tissue which is a negative inflammatory marker. Google it. Can leadtosexual exhaustion on predisposed individuals whose bodies don't regulate homeostasis properly.

Intresting artical ive done edging & do not suffer Blue Ball syndrome but the problem i now suffer is not being able to ejaculate i get no sensitive feelings around the Glans Head any more to get me to the PONR i still get good rock hard Erections which is good but i can now masturbate for hrs until it then goes limp

...then you just take a break, and start playing with yourself later!
