What exactly does Tristan say? I've never read her book, but I know she is regarded as one of the highest autorities on anal sex.

I agree with Lou that relaxing is key when it comes to anal.

My own opinion on Jen's post is that as long as there is lubrication and patience there isn't anything to fear as far as the sphincter is concerned.
