Is it normal i can't trust myself alone with women?

I know myself well enough to know I can't trust myself to be alone with a woman in a vulnerable situation (ex. Alone in an elevator, passed out drunk, alone in an alleyway or backwalk, etc.) I know myself to be a pervert, and I'm aggressive and dominating.

I'm 27 and I hate I'm this way, I do everything I can to avoid these situations, and I don't let myself get drunk at parties. I'm absolutely fine in groups or with someone else around or out in public, and I do well in the dating scene, but I just can not be shown vulnerability. There are dates I won't do, like spending the night or hikes. I've warned girls before about how I am.

I want to attend therapy, but I'm afraid of being labeled as a predator or being thrown in jail. I've never acted on my impulses far enough to do harm, but I've stalked women on their way home, and I've forced girls into secluded areas before being caught and called out. It's not a sexual thrill or a fetish or a turn on, it's an urge to do harm.

I'm sick and I really want to find help and attend therapy, I just don't know how to go about doing it. I'm sugar coating it a bit, but to be blunt I'm basically a rapist who hasn't raped, and doesn't morally want to.
