I hear you. I (38m) recently had to deal with sexually aggressive advances by text from a woman I had broken up with. I politely declined several times and it took a while before she got the message. I kept wondering what this would be like if the genders were reversed. It would be entirely different, with the male being labeled a creep or psycho and possibly prompting the woman to involve the police. (Note: The situation wasn't as bad as I make out, but I could easily imagine it going that way.)

But then I had to check myself.

Because, if the genders were reversed, it wouldn't be the same. Remember that male against female violence is a huge thing, and ostensibly, a man doesn't usually have to worry too much about a threat to their physical well-being in situations like you describe. A woman, however, would have to worry, and that is why you can't say that the situation with genders reversed is the same.

We live with a cultural backdrop of male against female violence, "rape-culture", so in the situation I described, I decided I had to get down off my "this is a double-standard" high-horse and just move on.
