No, actually I ended up kind of "converging" towards this small boob aesthetic over the years of dating (and I didn't start with women who had small boobs). Only difference is that I didn't really care about height.
I genuinely like small boobs because you can kind of hug a girl tighter. Getting kind of crude and sexual, that translates in the bedroom in missionary position where you can kind of more easily maneuver closer to her, go tighter in lotus, etc.
That's not to say small boobs are "better" in any way, it's just that this is the preference I settled on. Yet some guys will even go so far as to call other guys "gay" or "pedo" for liking that. I think they're missing out on all the subtle features that make a women feminine besides just big boobs and ass.
The only thing that would make it creepy and perverted is if you liked those types of women because they reminded you of children and you're into that. The personality thing is totally normal. I've seen that a lot.
Why is that again considered perv if that's just your type? Everyone has a type and so do you, which is totally fine. I like that you like short girls as I am one myself, nothing wrong with that for example :')
I openly state on GAG that I prefer short petite girls with small boobs. It is just my preference, but at the end of the day, I'm not going to reject a tall or chubby girl with bigger boobs if she has a good personality. THAT is so much more important!
