This guy I'm seeing is straight as far as I know. I don't know his exact straightness percentage and I don't want to ask him because he might get all sensitive about it. So assuming he's 100% straight, I want him to experiment with his "posterior" with me. If a guy's g-spot is in his ass, life is too short to not want to discover this heavenly place. 100% straight guys: if the girl you're seeing wants to shove something up 'there' would you agree to it? Or what will she have to do to get you to agree to it?
