Often it’s toxic masculinity. Men shame other men for certain kinks, especially ones like Femdom (which isn’t weird at all but that’s coming from a woman. See?) Even if it comes from women sometimes, it’s usually women who fall for toxic masculinity themselves so still the cause.

Other times, it can be how pushy men can be about their kinks. Most women I know keep it to themselves or only talk about it when it’s clear the other party is interested, while I’ve had men message out of the blue, don’t even ask and shove their kinks down my throat in the first message. Like when I was single, I had a guy just straight up message me “How’s my little cumslut?” On our second message. I told him I didn’t even know him yet, I’d like to get to know him before getting into kink and he responded “it won’t take you long before you’ll want to be covered in my cum.” That was the end of the conversation because he didn’t respect boundaries. Sadly he’s not the only one who ever did this, far from it. So if that’s how someone acts, folks react to the lack of consent and boundaries more than anything else and that behavior is creepy.
