HOCD or discrimination against men?

I'm scared. I'm a lesbian with straight ocd, and I'm not attracted to men, but my brain keeps throwing at me "it's not that you aren't sexually attracted to them, you're just discriminating" and I'm here like NOOO! I have nothing against them but dick is gross! Then my mind said "you're just saying that because you don't want to be viewed as straight/bi" and like UGGGH I feel like it's true!??? But it's not!!!
Help me..

Your sexual orientation is not discriminatory in the legal/social sense. You're not denying men the right to vote, access to housing or profiling them. No, you like women, that's what your directed towards. Im a straight man, but I have the fear of turning gay. I spike when I see nice looking men and my mind wonders if every thought I've had about women is a lie or forced. It's a constant struggle. Neither one of us wants to be with a man, and our reluctance/fear of that feeds these obsessive thoughts.
