He said something to me like "women often say they won't have sex early on, or 'I make a man wait' but then reality is different". I didn't know that was a thing.
I don't know whether this will make sense to you or, perhaps, feel like too much to take in. If I'm not explaining well, perhaps others will be better able.
What he's describing is simply that women sometimes change our minds. We're free to do so.
We can go from 'No sex' to 'Sex, please!' if we wish.
Importantly, we can also go from 'Yes, now' to 'No, stop'.
The person we're with has just the same rights. A change in consent should always be respected.
A lot of people - especially men - fail to recognise women's full agency. They see women as sexual gatekeepers. The man, in this framework, is trying to get sex from the woman. If she doesn't consent, it's because she wants something in return.
Maybe (he thinks) she wants dinner, a relationship, or just to make his life difficult by exerting power. The point is that he earns a right to penetrate her, and she should grant it as his reward.
The idea of a woman either wanting or not wanting sex - or sex with him, or at that time - features nowhere in this picture. She is merely a warm hole putting obstacles in his way.
Men who think like this have very little concept of female desire, let alone the real meaning of sexual consent - which is enthusiastic, ongoing participation.
As well as the phrases you've quoted above, they use terms like prick-tease, cock-blocker, mixed messages, and 'no means maybe'.
These are all low-key rapist expressions. They don't automatically mean the man is a rapist. But almost every rapist has used these terms to express his feelings that women somehow owe him access to their bodies.
Going forward, I'd advise using your words very clearly. If you can't find words at any point, take this as a sign of overwhelm and call a decisive halt to proceedings.
If you're with a man who uses any of these phrases, back off. They demonstrate a sense of entitlement to penetrative sex and, just as importantly, a lack of respect for female agency.
