I agree! I love getting my face between her cheeks any chance I get. Its intimate and naughty and makes her moan and gasp in pleasure and all that gets me really excited. Its also especially important when introducing a partner to anal play. When she realizes how much I love EVERY part of her body and how much her pleasure matters to me, she can relax more and trust me. And we all know how important relaxing and trust are during anal sex.
I always thought women should have a rule "If you don't lick it, you can't stick it!" no matter which orifice is involved!
