As a social 420 user I do have some thoughts on this. A few of our swinger friends are 420 friendly, and in fact do smoke at some parties. Personally I have only used it one time at a house party. The host and I shared a joint, and then we went off and had a pretty good time. I don't believe the sex is actually better after using marijuana, but the relaxed and happy state it induces leads to a more pleasurable experience. Watching a certain tv show or video might be fun when sober, but the user may note elevated response levels to it after use. Following this logic, I believe the sex is perceived as better and more fun. It can also make everything feel somehow better because of the altered mental state one enjoys while "high". This is why we call it being "high" because we feel good and elevated. Marijuana is classified as a mild hallucinogen, probably the reason things physically feel better when using it.
I do caution anyone thinking of having 420 sex, as in most jurisdictions it is illegal. :rolleyes:Don't do anything you wouldn't want a cop to see. :cool: Also, if you are going to someone else's house, make sure they are 420 friendly... it is NOT cool to bring something to someone's house that they are not cool with.
