Scorpio and Leo, they seem to think of sex all the time.
Lol you sure Pisces not into it? Maybe they just "act" decent, and i once dated a pisces guy who was just like that, most pisces men i know are quite sexual. I believe you have to seduce the pisces men, like make the first move.
As for Virgos, one of my best bud is a Virgo, he well ... he does seem to have less interest in sex.
