rogerfederer saidit hurt my feelings bc honestly who prefers jacking off than to fucking a guy's butt?
Rather insensitive of him. It also tells me he may be spending a lot of time jerking off and has conditioned himself to need a very tight fist, which not all asses can match. And/or he just doesn't like anal - it's a fallacy that all gay men do.
Have you asked him a reason for this preference? If it's the feel and tightness there may be things you can do to increase his pleasure with anal. Or he'll be the top long enough to please you, but then you'll actually get him off next with your mouth or your own hands. Some guys take turns like that, doing for the other what he likes best.
