Sex while high is the best thing that has ever happened to me in life! I don't usually smoke...I only got a few whiffs of the stuff my boyfriend was smoking, and I got high...I was laughing the entire time, and he started laughing too...and the touch...everything was 5x as sensitive for some reason. It was...euphoric!
I really like having sex while stoned, it's just a matter of the sense of touch being heightened, everything feels better and if the person you're with is someone you really care about, it's like nothing else exists and you want the moment to last forever. I havent had sex while high and wont in a very very long time, but honestly right now is just as good. I've discovered it's a matter of comfort, weed helps you relax, but it's something that's very easy to do with the right person.
