I exchanged some e-mail with her about ten years ago. She's actually not into anal per se and is a little mystified by the fascination fans have for anal scenes: she thinks anal scenes are gay.
She says she's a masochist, and draws a clear difference between that the usual BDSM. She's into the M more than the S.
I assume a petite 5'2" girl having a young & hard Sean Michaels go balls-deep in her ass might satisfy her masochist itch; she just couldn't figure out why a straight guy wouldn't go for her pussy instead.
If you look at her Anabolic Gang Bang Girl scene you'll see that she's pretty bruised. That's because her "Daddy" gave her a flogging to warm her up; Chris Alexander though they wouldn't be able to shoot the scene after that was over.
Her scene in
Kink with Rocco Siffredi is my favorite.
