Usually we have good, hot sex when we've been drinking... it's a lot of fun, and I tend to request anal more when I'm drunk (it feels a lot better then, because I'm way more relaxed anyway). Red wine does the trick especially well.
Of course, the time that I got trashed at ktspktsp's work gala and tripped down some stairs on our way back to the hotel room (he helped me up), and then promptly threw up in the toilet (he held my hair)... THEN asked for anal?
Yeah, not so hot. Good on my husband for not taking me up on that offer, not that I remember much of the proceedings anyway.
