My first experience of anal was a poor VHS copy of an American porno, which pretty much disgusted me. Didn't take long to get into it, however (thank you, Tanya Foxx).
I couldn't believe my eyes when I first saw ass to mouth, and had to rewind the tape a few times to make sure there weren't any cuts (FYI, Rocco Siffredi fucking in a Teresa Orlowski compilation).
I then discovered Private (in the days when PW was shooting for them with drop-dead gorgeous anal-friendly babes - the Tower, Sweet Baby, the Gigolo etc as well as Triple XXX and Private Video Magazines) and by then the rest was history. If the girl didn't get sodomized I wasn't interested.
These days I regularly fuck my partner up the arse and she even does A2M if she's feeling horny.
How times have changed.
