Why do guys like boobs so much? All they are are two sacks of fat that fill with milk when you're pregnant and get saggy when you get old, amirite?

Because we don't got dem. and I NEED them!

Because it is like magic when they appear on a girl because a guy would have to get fat to get boobs but it isn't the same

So? girls honestly never think about penises on a regular basis unless they're a perverted prostitute or something.
