What’s your vote?

If my sister keeps telling my parents I’m gay or a boy when I’m clearly a girl and I’ve dispelled all rumours by constantly telling people I’m straight but just have never had a boyfriend (because at my age that’s rare) am I then gay if I’m clearly NOT identifying that way? Would you think I’m gay if I was firmly telling people I am NOT? But due to past mistakes my sister has said this to hide her relationships with girls? And she wants to keep calling me gay until I like it? Am I then gay to other people because of her starting rumours?

How hard this will be for me now, having to try and find a man to be with me will be nearly impossible with her constantly telling me to like being a way I’m not? This is nearly impossible for me to accept she is using me to hide herself.
