Not sure this is in the right sub-reddit but here it goes.

In my friend group there is a girl who has just turned 16 (live in the UK so legal age). I was at a party/BBQ with that girl who told me on the night that she has a crush on me. Im really not interested at all, an told her i wasn't in which I thought that would be the end of it.

I went upstairs to the bathroom to come out and she was standing there. Im quite a skinny guy (5"11, 10 stone/145lbs) but the girl is around the same height but is a bigger girl, and weighs a lot more than me.

She forced me upon the wall an tried to start kissing me and started groping my crotch, in which i pushed her off me.

She then ran down to all of our friends an told them i punched her.

Obviously i denied it an told a friend what really happened but still, people in the group believe her.

I was just wondering what i could do, after being told that i should "man up" and people calling me a "faggot".
