I’ve been taking to this boy for literally months now and the whole time I just haven’t been sexually attracted to him and I don’t know how to tell him

When we kiss I don’t like it and it’s not me because there’s other I like

I know I’ve been leading him on but I thought it would change and it hasn’t and I still don’t fancy him

I know I should be honest but I don’t wanna be a bitch

Please help! Xx
