A strategic player will wait the month and more.
He'll be entertaining other prospects at the same time, as always, so it's no skin off his nose.
Waiting is no guarantee they still won't dump or fade when they get sex and no guarantee that they'll decide they're not feeling it and don't want to commit after a while.
There are plenty of women in marriages and ltrs who had sex with those men immediately or quickly.
My sister was married to a man for 20 plus years - they fell into bed on their first proper date.
It depends on the intentions and character of the man, and how things pan out.
(It also depends on the woman's character. I've known a few players who got gradually sucked into a relationship with a woman who they thought they were just messing with/shagging initially - over time. And because she was perhaps also rather harem scarum, indifferent and not focussed on commitment. And because they turned out to be compatible.
The player/Messer/commitment phobe isn't going to commit whether the sex started one month or two weeks or three months in.
It's not as simple as this.
In terms of sex early/at all; I agree most women are much more vulnerable to oxytocin than men. This means a higher risk of pain of it doesn't work out the way they want it to.
They are also more at risk in an unwanted pregnancy situation. A termination or a child for life are both things the man won't have to face. He can get away with CM or minimal co-parenting.
Likewise stds often affect women more than men due to anatomy.
All these are reasons to be circumspect. But not some quasi religious, sexist, objectifying theory that make women the gate keepers of sex, that make sex something women give to men or hold back from men etc.
