I lied about being gay

I am a girl in an all guy friend group, a while ago we started hanging out more than just at school, and rumors of me sleeping with them and being a whore started spreading. Once when walking beside my male friend to class, I was stopped and asked if we were dating by the same dude who had asked my friend how much he would have to pay him to fuck me. In a stupid quick response i told his that I was lesbian even though I’m not.
I’ve seen him tell others about it, some of them who’ve started ignoring me. I don’t know what to do. I’m not in love with my buddies. I just want to be able to have friends without being labeled either as gay in an offensive way, or a slut.
