A question about the fact that women make some men wait for sex, while with others they do it right away

So i start by saying i don't believe 100% that women make wait guys they care about and have sex guys they don't care about.

Too many times the reason, and there is nothing wrong, is simply attraction.

Sometimes a guy is so incredibly attractive for the woman that she wants to have sex immediately, while the other one is attractive but not so crazy attractive that she fears to lose him because she says "ok he's cute however not that hot that if i don't have sex ever with him i regret it".

In my opinion most of the times is the guy's fault.

One is simply good at creating sexual chemistry. He wants to have sex with the woman, flirts, she understand what he's doing clearly and she eventually accepts.

For many hears i thought i wasn't getting sex because i was boyfriend material, because i was good etc but it is not true.

It was because i wasn't doing any moves. The dates were too formal, just to people speaking and getting to know eachothers.

Of course women will say i'm a green flag because i want to get to know them and we will not have immediately sex.

But now i ask myself. If i wanna have a relationship with a woman but also immediately sex, how do i do it?

Because if i work for both, the woman can sense mixed signals. She can be confused and therefore not willing tl have sex because she could fear i'm fake.

Maybe she thinks i act like i want a relationship but in reality i only want sex and so if i try the first date she rejects me.

So i'm asking myself should i only approach from the start like i only want sex, so she sense that i'm there only for having fun, maybe she accepts and AFTER sex showing her i'm interested in having a relationship with her?
