Can someone please genuinely explain this to me? This comes up a lot on r/dating its one of their top posts rn.

A guy comes on and says he's been accused of leading a girl on by taking her on dates, or cuddling, or holding hands, or giving too good head, cooking them breakfast or something.

All the girls ask if he was up front about wanting to be casual, he always answers that the conversation didn't happen until after they've had sex.

He gets accused by women of leading girls on and being a fuckboi since the conversation didn't go the girl's way.

He's called a liar, because he lied by omission and should do the honourable thing now and let her go because he's such a piece of shit.

But title, why is it just okay for her to assume that he's moving towards a relationship but he's a devil for assuming that she's just down for some sex?

Please explain.
