As someone who has sampled both, I would say.....listen to castle!! It really is like a tattoo, we've all got our different opinions, but you're the one who has to live with it. I've experienced natural boobs that were wonderful, natural boobs that left quite a bit to be desired, fake boobs that felt wonderful, and fake boobs that were like "whoa...I hope these things don't pop if we get too rough...". Just please, please, if you get 'em, use the method that doesn't leave those funny looking scars!
Now that I've made myself out to be a complete manwhore.....I'll be at circle bar on main street in venice tonight, so all you natural and fake breasted women, come have a drink!
