Yeah, I let my wife know I was posting on a boobs thread, just so I wouldn't have to worry about her catching me in the act. Take the initiative and strike first!
I'd agree with Terry about appreciating a wide variety. It's normal and cool to have preferences, but I think even with those, all kinds of types (of looks/bodies) can be sexy. As long as they aren't extreme to an unhealthy degree, as mentioned.
I love those opening models, but they certainly aren't the only example of sexy, is what I mean. There are all kinds, so let's enjoy them all!
