As far as breast size goes i have had both from first wife to the second wife. All are great no matter what size. But as for me i like small to medium size.
Is breast size similar to many (not all) of the responses I've read on the thread about "honesty" and "penis size"? Many of the comments were "it really doesn't matter," especially if the body part is attached to someone you're in love with.
I also have had very big and somewhat small....and I enjoyed both. They were attached to someone I loved, so it was all part of the fun!
