Should I cut her off ?

I have this friend that really fast . I'm in highschool and she had sex with boys. She 15 with only 4 bodies but once she starts talking to boys she has sex with them. I don't want to be around her because I don't want a bad look on myself . People are calling her a hoe and her friends a hoe too. And if I hear that I am one too I'm going to be pissed . Should I cut her off or no?
