4-aco-dipt  I agree as being highly suitable for such activities, 5-meo-dipt is just euck for me all round.   5-meo-Mipt  on the other hand is everything foxy isn't.  LSD can be exceptional.  Shrooms i find to be pretty sexy too.    Sex on DMT impossible you say ? at the peak of the flash , well yeah   but in the afterglow of a vapourised nn or 5meo hit, or during / following an orally admin'ed  journey it can be wonderful
