Why do some guys not like getting their ass grabbed?

[Prettygirl102]

I was out walking with my boyfriend and I grabbed is ass he glared at me and lifted my arm back onto his waist, I did it again as a joke and he got really defensive so I just stopped. Why do so many guys not like it?

I'd guess either discomfort with that kind of aggressive physical contact, or (if it's more butt-specific) with the implication you might want to do more than just squeeze- a lot of guys are, to my mind at least WAY too sensitive to those implications.

That's a good question, I would be honored with my girlfriend grabbed my ass. I'd return the favor and grab hers

He likely sees it as a way to test the waters for more butt play in the future.
While a bit homophobic, I wouldn't consider it terribly uncommon.

I don't know the science behind but I know I don't like it.
