Why I copy book? Why not?

This poor ersatz Martian is saying, by your own report, that sex is a way to be happy together. I go along with Mike this far: sex should be a means of happiness The worst thing about sex is that we use it to hurt each other. It ough never to hurt; it should bring happiness, or at the very least, pleasure. There is no reason it should ever be anything less.
