My husband uses it legally (he has his medical card) and I do use it. For me I get super horny when I am high. It doesn’t affect my husband so it’s not a problem. I don’t use drugs or medication during sex often but for me it’s not always bad. Sometimes it helps because it allows me to get off much easier.
I love high sex....things just seem to feel more intense and tingly. I don't do it all the time, but it's awesome! Sure I get dry more easily, but we got lube and a bottle of water next to the bed. It's fun!
I've had sex high on all kinds of drugs...rather than enumerate all of them and/or make myself look like an unrepentant former junkie, I'll just say that sex on 98% of them was either pointless or over-rated. Sex on acid is interesting...that much I'll say
In my 20s I was a full-time stoner for about a year, and sex whilst high is AWESOME...until you haven't gone a day without weed in a while. Then it progressively gets a little less enjoyable than it was in the beginning. Eventually, it gets to the point that it feels about the same as having sex sober.
