My guilt comes from a variety of sources: lesbians saying that they don’t care about size (which is perfectly valid), women with big bosoms complaining about the pains that they cause (also valid), and scientists finding a correlation between misogynistic boys and a preference for enormous knockers. I’ve even read that some girls have ended their lives over dissatisfaction with their sizes. Basically, I have this impression that a preference for massive mammaries is something that only ‘trashy straight boys’ have, therefore I feel guilty by association.
That said, I try not to be a jerk either: I don’t shun or mistreat ladies for having small breasts, and I wouldn’t fight tooth and nail to prevent somebody from getting a reduction either. As long as she is happier with her smaller breasts, that’s great! I’m happy for her! And I don’t mind being friends with somebody who has small breasts either! So I like to think that I am not that shallow of a person. Also, maybe this is usual but I tend to associate big boobs with power and I would much rather be dominated by huge honkers than vice versa.
None of this erases my guilt, though.
Is my preference a problem that I should try to fix or am I worrying too much?
Your preference for your own body is about you, no one else. Personally, I never wanted huge ones, but I wouldn’t mind larger if only because many clothing styles are tailored for them by default. But none of that is what’s important. It’s your body. Be you.
