best method (enema)

okay, so for most of my sexual life it's been pretty much oral only.
my BF and I have decided to try anal, with me being the bottom.
basically i have no idea of what to do to prepare down there,
and i would really appreciate any help you could give.
:D
what should i use?
i've read a bit online, even one bizarre blog involving coffee,
but i'd rather hear personal experiences to help me get my head around this.

Here's what I use. Buy Colt Shower Shot - TLAvideo.com It is the Colt Shower Shot. I have used it for several years, usually once a day while showering in anticipation of sex with my lover. Occasionally the prep was in vain, but for the most part we have sex at least once a day. I prefer to clean up a half an hour before going to bed to allow any excess water to be absorbed by my body. Let me know if you have any questions.

interesting. thanks!
