Do you have a therapist?

Yes lots of men are jerks and you should be afraid of them but it's not good to live in fear of all men. But with that said if you get to a point where you aren't afraid of all men that doesn't mean you should date one of them.

It sounds like you at least have some bi-sexual leanings, I would suggest looking into a lesbian support group in your area if there is one. And talking to your therapist about this if you have one.
