I feel like a whore

So in my past I have made out with lots of different people, I am ashamed that I have. So since about 6 months ago I told my self I would only do these types of things with someone I truly care about. However, recently a guy friend who I had made out with a while back and I where hanging out and we made out and (through my clothes) he felt everything and it felt so good. I know I don't want to be like this but when your body starts to cloud your mind, it's hard to stop. How do I stop? I don't want to be like this anymore, but it felt good that I think about doing it again. And don't give me all that body/sex positive BS. Just please give me some genuine advise.
