I'll also go with... D. All of the above!

The bad music (do they ever play any current, known artists?), the talking/moaning not matching the scene (like those ole black & white spagetti westerns but naked?), the fake boobs, hair, nails, too much make up, and the anal to mouth definetly ewwww!!

And high heels in bed?

Saw one where the guy had white socks on and there was a hole in the heel. Realistic maybe but ruined it for me.

And does she ever do anything besides moan?
