Ok well here is my problem, I'm very sexually active, i have 3 partners i have sex with, i recently was exploring EXTACY, and i loved it, so i did it a few more times, well This week alone i've done it 5 times in less then a week, and i take usally 1 pill everytime i do it, at first it was awesome, and now almost everytime i have sex, i go limp after 5-10 min, and won't be able to get hard again, i get really upset and frustrated when this happens, so from here on out im done taking EXTACY, i just want some imput on whats going on with me? I've never had this problem before, it all started when i took the E, i was always hard and stayed hard.. everytime i have sex now, thats all im thinking about is i better not go down or soft, im not sure if thats my problem or not? people told me my serotonin could be depeleted, i just want to go back to normal?
