Vagina 100% I enjoy the other one…well I'm starting to. My fiancé recently started doing it and its my first time experiencing it in full. Vagina still wins though.
Anal penetration will get better and better as you become more and more welcoming of your Fiancé back there; as you begin flirting more and more with your derrière, letting him know what you like about the act, etc. The more you give it, willingly and joyously, the more you will receive. Exponentially. i promise you!
But most worthwhile things are, right? When Master is owning my bottom, thrusting deep and true, that is the closest thing to heaven on earth. i LOVE worshiping Him with my mouth and welcoming him in my pussy... but cock-in-ass is the ultimate.
Anal whores are very easy to find. Go to the bar and look for girls who show off their asses in some way, either by very tight clothing or whatever draws attention to them. Your chances are very, very high (over 90%) that such a girl loves it in the ass and she is definitely worth spending money on.
My vagina is my favorite. Position wise I can see them better and we can be closer. I feel that I have served my bf/lover when I have let him cum in me there. Really the only time I favor anal is when I am having my period. Some day, I would like to try a double penetration, with the right guys.
