I'm 22 years old and new to any kind of rec drug. I've had mdma a couple of times and it was hard as hell to get it up. I heard that coke gives some of the same feelings that mdma does but with a little bit more control but a shorter lasting high. So I did coke a couple of nights in a row. Pretty good stuff, I must say. Sex on mdma was damn near impossible. Sex on coke happens but it's a pain in the ass trying to get it up. Most guys I know have no problem at all effing on coke. In fact, they say that they're much better. Is this just a problem that I have with drugs period? I consider these guys addicts as well so does it have to do with their tolerance to the drug? I won't let my coke use get as out of hand as their's and don't want to get to that point to have good sex while high. Is this something I'll just have to deal with or can casual coke users build the same type of tolerance?
