Is it normal to find this cute?

I saw a picture a guy drew of his mother, naked and all (very sexy, too), for Mother's Day. I found it weird, of course, but when I read a comment stating that it was sweet that the guy who drew it would cast aside his preferance for men to "please" his mom on Mother's Day, I couldn't help but find the the idea cute. I feel messed up for thinking this, though.
