You may have a mother complex.
I don't care for huge tits. My first wife was a 32D, 36C depending on what fit her better. In reality she was more than likely a 32 DD or more as her under breast was 32" but most places at the time (1990's) didn't have bigger than a D bra that looked "sexy".
The bras for huge tits at the time available easily/cheaply looked like medical gear.
Then you have all the issues that go with big tits like back aches and the like.
I like a B-C. I haven't done titty-fucking since I was in my 20's as it's really not that great. To me it trails way behind her mouth, hand, vagina, ass.
I like a curvy woman mostly, some athletic ones are a turn-on though.
My biggest turn-off is skinny legs.
