Well, are you aware of the website 4chan.org?
If not, then I'll just tell you I am quoting the creator of the website, because I find it funny. (It was a joke then, it still is.) Everybody thinks I am serious, lol.
In any case, no, cleavage sucks, it hurts your back. But you wouldn't know that now would you. (I have had COUNTLESS girls tell me that, and quite honestly, I feel for them, it has to suck.)
