Weird experience trying to have sex on cocaine

Does anyone else find it nearly impossible to have sex on cocaine? I tried with my partner while we were coked out of our brains and we 1. Got too distracted talking about random shit or whatever came to our coked out speedy brains and 2. Erectile dysfunction issues. However he told me he's had sex with heaps of people on cocaine perfectly normally and it's making me feel bad. But sex just seemed almost impossible on cocaine. I dont think cocaine is a sex drug. What do y'all have to say about this?
