yeah k would be really weird and dissociative.
maybe sex on e is a guy thing? does it enhance pleasure or something for guys? it really doesn't work for me, even though touching feels good in general.
well its more sensual than sexual, but sex feels great on it too. maybe not at the peak (which is a bit disorientating to say the least, plus impossible to reach orgasm as a guy - but maybe thats not such a bad thing). but certainly on the way down one of the best experiences if you ask me.
also worth a try: ghb (be careful with this tho.) - staggeringly good if combined with e and sex, plus 2cb which ramps up tactility to space-age levels.
although pretty much anything works for me i have to say, bar disassociatives. i think its got more to do with my mind sometimes, than the drugs themselves.
as an aside, are you a woman? don't take offense but i kind of figured you were a gay man for some reason.
