Another poster described being able to get almost orgasm by playing with his nipples and wonder if full orgasm is possible that way.
Well for me it definitely is! Like him it is easy for me to get near to climax by playing with my nipples but that final push over the edge is harder. Not least from the fact that the temptation to grab my cock and quickly finish things is often overwhelming. If I can resist that I find getting quite rough with pulling and squeezing my nipples will eventually bring me to a very, very intense orgasm. Another technique - one I borrowed from reading ladies contributions on this site - is to use electric toothbrushes on my nipples. The feeling of one on each nipple is mind boggling, although it can sometimes be too much and make them sore. I keep 2 old toothbrush heads that are nice and soft and find they are ideal stimulation: new ones are just too rough.
Love to hear from other male nipple masturbators.
