ashamed of myself

I just got out of a decently long relationship, since then I've hooked up with 5 guys. It was never my intentions to hook up with some of them because we are just friends, but it's happened. I never saw myself as easy but I feel like a whore and I'm ashamed of my decisions. I still want to be that innocent girl that I once was. In the end I'm the only person that knows the truth, no one else.
