I need advice on what to do?

Firstly I don’t think I’ll get a lot of help here because there was a poll on here and only 8% are lesbians, Whenever a man talks to me thinking I like men I always tell them straight I’m a lesbian and they never take it into consideration and still talks to me in the way u would with a straight girl. Yes I do block block block but it’s not just one person it’s mostly every man that talks to me. Idk what to do think I need a tattoo on my forehead saying #gay

They look at me I bet and think I’m straight
