Let me take a short poll.  I'm not into speaking greek and the hole butt thing is a turn off.  I don't much like looking at the underside.  I do like the form, but don't bend over if front of me.  What are some other takes/comments?

I havn't tried greek yet, but one day I would. When doing 69, I do however like to see the little butt hole and sometimes even like to pt a finger or two up there if it seems that it will enhance what my lips and tongue are doing. When DATY and the legs are up and the butt hole is exposed, I usually do like to play around there a little and this usually gets a good response.

It's a bit tighter than the vagina, but not by any great amount.

The real thrill comes from the provider's interest in it.  Some are just ga-ga over it and when you perform is with them, their feeling of ectasy is contagious.

When you find the right lady with that perfect butt you will understand.  Nothing better.  Just mu opinion.

And you don't need to jam something in to stimulate it, although that goes for pussies as well. I just kind of feel around and if she's into or4 turned off by anal stimulation her body language will let me know.

I love dogging a girl with a nice ass. It's a huge turn on for me. YMMV

I love the rear view.  It really gets me going.  I'm a relative newbie to the hobby, and my civie experience didn't include ladies who liked much attention back there.  The other day I spent some time with an ASP who was REALLY into though and I explored it a bit ... quite a bit, actually.  The conclusion I came to with that single experience was that if the lady is into in then I generally like obliging her and find certain aspects of it very stimulating.  When we got down to visiting greece though, it was only okay for me and nothing to really seek out.
