I think you should honestly take a complete break from relationships. I slept with 13 men and 2 women from the ages 14-16. Some of it was rather unwanted and "pushed" on me, however I allowed it in the end, so I don't consider it rape because of that. But I know what it feels like to feel used in the end. However I was molested in my sleep by 4 different people LOL! Yeah it's not funny, but I don't take it too seriously. I did the first time but after that it was just annoying.
We seem to have similar experiences in that regard. What I did was I dropped relationships and sex out of my life for 3 years (this break started at the end of my year being 16 and ended when I was almost 20). I did this to develop myself and personality on my own. It was quite nice, but I have to say it took balls since most people on that kind of path don't make a change like that. They just keep on keepin' on. I'd say I'm much more well rounded as a result.
