Fortunately, I have done some groundwork in this department.
-From the "guy" side I can report that anal sex is kinda novel, for a short time. It really doesn't feel all that spectacular. Its nice but the reality doesn't live up to the reputation.
(Damn, that sounds f*#k'n boring. Read on, it gets better)
-From the "girl" side, I have a gay couple next door who do ALL my "anal-recieving" research. They tell me much the same as whaywardj said in post #5. Although THEY were a tad more graphic.
I also agree that condoms are a MUST.
