Self Worth and Sexuality

So I've recently turned 30 and this being a milestone year, I want to make huge changes in my life. Starting with men. I have very low self worth and self esteem and i tended to let men use me in the past. the worst was staying with my abusive ex after he tried to drown me. Now, normally I rush into relationships (at least the physical part of it) and then I realize how terrible of an idea that was too late. I have been used for sex so many times I've lost count at this point. been drugged and date raped and beaten and made to be the hookup girl or nothing more than a side bitch while the man goes after his main course. but now I feel like God (or a higher power) is speaking to me. I lost my faith a long time ago. but lately I've been feeling like something is moving my spirit back into the light. like I need to value my body and soul before I let another man use it. So. I am not going to have sex with another man until he puts a ring on it. is this unrealistic?
