I bought the saline version for my ex a few years back. It changed her whole attitude to be honest with you. Yeah, I liked them, but she ended up wanting to show them to everyone but me. LOL
As long as you've got a solid relationship, that's fine, and ENJOY.
As far as the softness goes, the women are supposed to do the "exercises" in order to keep from building up too much scar tissue. I got a close up of her's a few months ago, and they were hard as a rock now. Looks great in clothes, but not a whole lot of fun in the sack.
I love the Naturals. Much more malleable. LOL
