Is there such thing as having boobs that are too perky?

I think my boobs are too perky like I'm a 32D and they don't sag at all like I constantly have major cleavage with whatever bra I wear but I always have a little gap under my boobs to the under wire. Is that normal?
And also any bra I wear I always have nip slips like they don't naturally sit in the middle of the bra
