Can I recommend visiting a women's support charity or group, specifically one which offers support to victims of rape?
I have been through some similar experiences; was at a really difficult and low point in my life, and was raped by two men (together...).
I have been through a great deal of counselling and have done more than my fair share of naval gazing and battling some deamons! However, and this sounds completely clicheed, once I healed the things which were making me sleep around, I actually met a lovely man who treats me beautifully and who I have a great sex life with. Say what?
It was a vicious circle for me. I was molested as a child so later in life sought validation through sex. Thought I was being super free and liberall, when in reality, I was just picking a series of cunt fucks who just made me feel worse about myself! Then the cycle would go again- feel shit, look for validation through sex, be treated badly or not be satisfied or feel used, begin cycle again.
The culmination / breaking point was picking an abusive ex, who raped me with a friend when I finally mustered up enough courage to leave.
My advice- keep your legs closed for a bit whilst you spend time loving yourself. Masturbate and figure out what you want an what works for you. Wait to have sex if you meet someone new- and be honest with them about your background. Weeds out the ass holes!
My husband has been super supportive and really has helped me recognise and work through issues. They still rear their ugly heads sometimes but luckily I recognise them now and can put them in their place.
Hope this helps.
