On the surface it would seem that you're a bit confused about your sexual orientation.
However, I think your sexual confusion may be a symptom of a deeper, unresolved emotional issue. The fact that you mentioned that both your mom and dad didn't touch you makes me wonder if your sexual confusion is related to the feelings of deprivation that you felt as a child. In other words, if you felt a yearning to be touched by your dad, and he never did touch you, it is likely that you would be yearning for a man's touch in order to make up for the physical closeness you didn't experience with your dad.
When it comes to women, you seem to be yearning for verbal contact. You want the women to talk to you and if they don't you're frustrated. Perhaps your mom didn't talk to you enough? I get the sense that you're very angry with your mom, and this would explain why you often feel so angry with the women you see. Your anger is expressed by your using women sex and then dropping them like objects for whom you have no feeling. In this way, your anger is being expressed in hostile actions.
The problem for you is that you aren't completely aware of how you feel. Instead the buried feelings are being expressed in actions (masturbating while thinking of men or using and dropping women).
While actions may temporarily release your angry feelings, they don't help you resolve the problem. To resolve the problem, you need to become conscious of your feelings and put them into words. Actions aren't a substitute for the healing power of words.
I would say that it would be good for you to become clearer on how you feel towards both of your parents. Identify all your feelings and give them voice by writing in a journal or speaking them aloud to a trusted friend or therapist.
After you work through your feelings, you will finally be in a better position to see more clearly into your sexuality.
