I think you may know the answer yourself. Correct me if I'm not that you are the same girl that allows older men to touch you/you touch them, then you know it's because of the abuse that you've been through in your life.

You need constant attention, whether it's from not getting attention from your parents or from being manipulated for so long. There is a part of you that is missing that your try to fill with the affections of older men.

Have you been seeing a counselor about this? It could really benefit you from being seen, preferably by a female counselor.
