Men on dating apps.
Unless it's unusual looking or massive I don't need to see it lol.
I'm also really not interested in your interest in my underwear. Especially if that is your first message.
And then there's the endless married or attached ones, the ones that could be my grandad (ewwwww!) and the ones that want to be with a trans woman but don't want to be seen with a trans woman.
Sigh.
