Need advice

I've been with this girl for two and a half weeks and she is kind of a hoe. Shes been with 6 guys before she got with me and is only 16. I know some of them. She is fine asf and thick. Shes the only girl I can really be myself around and we have everything in common. The only thing is that I cant get her being fucked by so many dudes out of my head. What should I do?
