Help?

So I’m bi, but only a few close friends and my parents know. I’ve dated 2 girls, but with both of them I had to keep it on the DL. If anyone from my class found out I liked girls I’d get picked on and I know it. The only issue with keeping things on the DL is that it seemed like it was damaging my relationship with my partner, and it was harmful to them. I really don’t know what to do, should I tell my class, wait for them to figure out themselves or not date girls until I’m out of school?
