It depends how open you are I think, and how open your partner is. 'Cause I've only had sex with one girl, but we are rather deviant.
Doesn't matter if you don't believe it but you wouldn't know anyway.
But sex is pretty good, hm.
Here try this.
Get some really good lube, like Sex Grease, they sell it at your local Spencers, and jerk off, but it is warmer, and softer, like a tounge, and the pheramones, just make you that much hornier, but that depends on the person.
