While it is true to a certain extent that the sex tool can be used by either gender, it's much easier to use it on men. Biologically, men just want sex more than women. Most men can pretty much be talked into sex at any given moment regardless of whether or not they're in a heated argument at the moment... or at work... or operating a motor vehicle... yeah pretty much any time. This tactic just wouldn't work as often on women.

Also, there are certainly women who are able to admit they are wrong, and admitting wrongness is not easy for a lot of men either but men end up doing it even when they don't mean it a lot of times just so the woman stops arguing. I think men more than women would rather just say "I was wrong. Sorry about that" than continue an argument.

In my experience, a lot of women will maintain that they are right until the bitter end even past the point where everyone involved realizes that her position is outright ridiculous. It's as if admitting wrongness for a woman is like admitting that she is has failed as a person. But as you said, people's experiences are different. I have never dated a man, so I don't really know what it would be like from first hand experience. But I have friends who are male and female and even among friends I find that even with fairly trivial things that come up in casual conversation, men tend to admit they are wrong about something while women tend to just change the subject once they realize they are wrong.
