Question to the men and women out there

At what point are boobs too big? For me, there’s not a bra size too big. Even Norma Stitz natural boobs are a ZZZ cup. And hers are beautiful. So men and women, at what point are boobs too big for you to feel attracted to. For me, no cup size is too big. Now from J/K cup I’m interested. Anything after M cup and I’ll be infatuated immediately.
