The only signal I consider to be valid is consent for sex
Yup, and I'd also add if you're out her doing say cold approaches, then reading signals also applies here as well. Other than that, if we're talking about women showing interest, she needs to use their words cuz chances are, I may not even notice her if she's sending them, making me more likely to go for someone I am attracted to. It's only natural.
That is nonsense
Yea sometimes I get the feeling when they talk about men's issues, it's done in a way it talks about men's toxic behaviour being cause by not being more like women or some shit like that
