I hate it when guys think that sex can stretch a woman out, or that if it's tight she's still a maiden.

If it's tight (a.k.a. all fanfictions), it means that she's not turned on. If it's loose, then good for you, buddy.

But then there's the second thing.

It's all muscle and blood veins, nothing more, nothing less. If a woman can push out a baby and it can return to normal size, then you're not going to do anything, boys. Don't flatter yourselves.
