The feeling someone who's very emotional and/or very horny gets when they have sex with a good-looking person. There's no "yet," though, I'll probably never experience that.
I'd also like to experience heroin, but I never will because I'd get addicted (among other reasons).
That escalated fast... heroin? Why that particular pharmaceutical?
I don't know, I just think of it as probably the best-feeling drug.. not sure how I got that impression when I've never done any drugs. But also I like the
idea of a relaxed high better than an excited one
I did read that it's like having an orgasm for five minutes.. and then one or two other stages of niceness (whose description I forget) for an hour or two.
Maybe I want an escape, and being tranquilized sounds very escape-ish to me.
