I really, really like boobs...
Huge boobs are always a treat to the eyes. And the small ones are great too. I even love them sagging or asymetric.
It's always a joy to discover for the first time the tits of a women. There are a mystery. It's like opening a present !
I love all kind of shape or color. Big nipples, small ones (percied !!!)... every pair of tits is a piece of art from mother nature to me ...
So yes, I prefer natural ones.
In my humble opinion, "fake" boobs looks great in clothes but often not so much naked (there are exceptions of course).
Ultimately, the important thing for a women is to feel comfortable with her body, "fake" boobs or not.
PS: Don't care for the word 'fake', it seem pejorative, but I don't know a another word in english.
