I know exactly how you feel David i used to smoke a couple times a week and it was great, my sexual libido actually increased when i was high, lately on the other hand ive been smoking twice to 3 times a day and for the past month or so i have lost all interest in sex and my relationship has been suffering for it, ive been online trying to find the source of this and i think this is it, im 19 and have little to no sex drive because of marijuana, i decided to stop smoking yesterday and im glad i did, once everything normalizes ill probably still smoke but ill make sure not to smoke too much haha
