Primarily men? You better get with a woman then and see what she thinks. Every woman I have ever been with has thought of her tits as a sexual organ. They want them to be sucked, squeezed gently, etc. So "primarily men" doesnt enter into the equation here. I dare one woman here to say she doesnt think of her tits as a sexual organ, and I will show you a prude, lol.
As long as I get to play with her breasts, I don't care if they're sexual or not. I still consider them as mammary glands. They are purely feminine and for that, I am thankful.
I think topfreedom for women is great. If it did become more commonplace we would see less younger women having hangups about their body shape and size, and especially their breasts. Plus, the production of gossip mags that are out to make women feel like shit about their bodies will also decrease, thus saving some of the earth's resources. Go for it ladies!
