I like to masturbate while high on coke and weed. It makes my penis really hard and I am able to go for hours with several multiple orgasms. Is this harmfull?
Unfortunately I can't tell you whether it's harmful, or not. I just got really turned on while reading your post. It sounds amazing. . . wish there were more men in the world who could go for hours. ;-) Not a huge coke fan, but green is great. Best of luck finding an answer to your question.
