Asking Eric: My sisters-in-law think I’m gay

Dear Eric: My sisters-in-law think I’m gay. I know for a fact they have talked with my brothers about sexual attraction. Unfortunately, I have a real rough past with people making fun of me because I had a learning disability. The whole community put me down. I never tried dating in high school or after. I’m sexually attracted to women and would like to have a relationship with a woman. I have not had any luck with online dating. I’m afraid that my sisters-in-law will make the woman feel uncomfortable with me or my family. I have spoken to my brothers about their behavior, and they seem to not understand or go around it. I’m not sure what to do or how to handle my problem.
