In the past 2 weeks I've noticed that I no longer get aroused as easily as I did only a few weeks ago, I find it hard to maintain an erection, my erections (whilst still similar size) feel softer than they should and climaxing feels much less satisfying. My MDMA use has been fairly heavy the past 3 months, sometimes dropping every week. 2 weeks ago I had a particularly heavy night (taking roughly 0.8g) and I just couldn't get it up, trying to have sex with my girlfriend 2 days later - I was pretty bummed out but I didn't think too much of it. Anyway my girlfriend's gone travelling for a few weeks so since I've attributed my problems to missing her etc. Today though I made the connection that this all started after that night. Can MD cause a chronic reduction in libido? I'm only 19 so I'm finding this whole situation pretty worrying. Does anyone have any advice for me? Any info would be great. Also I fully intend to stop dropping until this is sorted out (and greatly reduce how much I take in the future). Cheers.
