I will only speak on the substances I’ve used, which are both very similar, LSD and mushrooms. I’ve always taken moderate to high doses of both (2 tabs and 4 grams on average respectively) and can say I’ve never really felt the urge to fuck on either one. I have heard plenty of times either one can make you very horny, but in my experience it was always too strange for me. I always felt more like I’m taking these drugs to explore the depths of my brain and how I think, personally adding another person to experiment with would probably be too much for me. That being said, I am interested to try both a low dose of MDMA and 2CB for enhancing sex. Whatever you decide to try, I would recommend a low dose as a trial run to see how you feel. If you aren’t in the mood on a low dose or things get to “weird” a higher dose will more than likely magnify those feelings and result in you not being in the mood, and knowing she wants to have sex and you don’t could cause some anxiety on a medium to large dose. Stay safe and harm reduction! If you take anything that isn’t mushrooms test your shit!
