I was wondering if any other guys orgasm like i do, i never really noticed before but i have been having sex with a older woman than myself and she brought too my attention that when i cum she has noticed that the muscles in my legs and pelvis as well as my penis go into "spasms, leg & pelvis muscles "and penis jerking and twitching spasmodically as the semen is pumping out , this lasts for about 10 to 20 seconds after my orgasm, I am circumcised and she also said that i have no "frenulum" on the glans of my penis, would been circumcised and no frenulem have something to do with the way i reach orgasm?????

im concerned about my penis, i play hockey in a junior hockey league, i wear a jock with protective cup at all times when on the ice.Im' a little on the large size, about 7 inches flaccid and find it my penis and testicles kinda cramped in the protective cup, when i get hit by a puck , my penis stings and testicles ache, will i have problems with my penis later on as i get older,??? also i am circumcised and the girls i have had sex with say they have never seen a penis glans so thickly calloused, will my penis lose its feeling if i keep playing hockey???
