Ok, I have been married almost 11 years now and my wife and I have a prettty vanilla sex life (she doesn't like to get kinky) and the last few times we've had sex doggie style, I have began to spread her ass cheeks when I am fucking her and she says it feels different; my question is what does it feel like when a guy does this to a woman (from a womans perspective) and how does it differ from noraml doggie style without spreading the butt cheeks apart (we don't have anal sex, it's vaginal) and can you tell me what is so great about having your butt cheeks spread apart during sex?
