I might bring my girlfriend on here to back this. For the past 2-3 years of my sex life (I just turned 20), I have had the ability to have a multitude of full orgasms during sex. On my 19th birthday I got off 9 times and stayed hard as a rock the entire time during 1.5 hours of straight sex. I shot every single time, at least 2 spurts. My girl also gave me road head once and I shot straight up to the cars ceiling (prolly not very impressive) Every single time I have sex I can get off and stay hard as many times as I please. I am also very good at controlling the orgasm as well. Is this normal? Btw, I'm not all that lucky with my penis size, but I can't lie. Girls have really like this ability to far (I cant...not stop, unless im physically worn out). My penis is 7.5x5.5 tops and like 3-4" flaccid. I am a very tall guy with a very high metabolism. Does this influence anything?
