There was a message thread here debating what is better in regards to anal sex, getting it from someone averaged sized or someone big. The arguement made for bigger guys is, while painful upon entry once they open you up, you stay open (as opposed smaller equipped guys where the receiver's butt continueously opens & closes). I wish I saved that link...it made for an
interesting read.
Personally I never had a big guy, so it's hard for me to compare.
