IIs there a way to brainwash yourself to not want a relationship with any man?

I want this to be humane as possible without degrading men. I've just never been in a good, healthy relationship no matter how well I've treated guys. I'm not wanting pity, I just want relief in my life. I'm not willing to take the pain with the pleasure anymore. Is there some mantra or psychological tactic I can use on myself to never want anything to do with the opposite sex? I don't want to hear the right guy will come along. Logically, I can't be bothered. Emotionally there's a very small but nagging voice that holds on for hope. Well I'd like to crush her, what do you got? I've already been single for a while but I want detachment to be organically apart of me without any hope.
