I once saw an independent SP and she shared a joint with me, after which she gave me a beer. 15 min later and in the heat of the session , the combo of alchohol and weed kicked into the craziest high I could remember. It definitely made the sex next level. The purple light she had on was also a cool effect that added to the experience. I really had to work hard to climax as weed for some reason makes me last forever. The drive home was a bit of challenge but lucky I live not too far from downtown.
On another occasion, with a girlfriend, we did shrooms and that led to a pretty crazy sexual experience.
Having said that, I’m not a regular user of weed but I do like to microdose mushrooms. It’s basically like having a glass of wine.
