Is "bottom" or "top" ONLY common?

For me its 100% bottom, while I love fucking woman, when I am with a guy I want to be the one that is being fucked!!!

I agree in that I want to be the one getting fucked...hard if you please...and after I want to be the one that sucks you back to life so I can enjoy your cock in my mouth, throat and while you are there shoot that load into my mouth, on my face and rub your cock through the cum and then back down my throat and repeat till you cum some more....I wanna be your cock sucking whore ;) better than cable I can be available on demand.

I am a bottom/versatile when I am with another man, orally or anally.

All bottom cock sucker here

Im like so many of you. I absolutely love women- every part of them, and love cock- in my mouth or ass or watching him fuck a girl. I was determined to learn how to 'top' , so picked a very cute butt on craigslist, and, tho he sucked me hard, I soon went limp in his ass. Sorry guys, I just dont get turned on fucking a guy.I really wish I did, cuz, theres so many more of us 'bottoms'
