Awkward

I guess sex can be a wonderful thing that two lovers share. Or it could be something that two people use to keep there mind off of other problems they have going on. Is that a bad thing? When you know sex, is nothing but sex. (Just thinking)
Would it also mean you don't value, your self worth? I'm not talking about having sex with multiple people. But just one person, that you wouldn't see your self with. But you keep crawling back, because your emotionally damaged.
