A fair amount of subtlety involved with this area.
Some good observations so far. The way I’d put one aspect of it, is that most “dating” is a form of scientific investigation. Testing each other in order to find out if you want to do more than just attend events occasionally with company. Sex, and the timing of it, is just ONE of the tests involved.
There was a hint from someone, that there is a sort of culturally programmed process involved. That is, each person is supposed to express interest in the other in various ways at various times, and our culture established both what interests must be expressed, and how they are expressed. All behaviors are used by each person to deduce the character, usefulness, and reliability of the other. Sex only SEEMS to be the most important, because there are so many emotional and physical involvements to it, and because our culture has long deemed it to have a great deal of meaning.
Anyway. A simplified version of how “dating” is supposed to go for most of us in this culture, is that each person signals some level of specific interest in the other; then one (usually the male, still, with caveats) makes some overt move towards the other. Next, each person begins testing the other in various ways. One of those tests, is that, just as the male is supposed to initiate contact (at least officially), the male is also supposed to be the first to attempt sexual intimacy. If he does so too quickly, the female is supposed to rebuff him.
Now, that’s where everything gets murky. If the male “makes his move” poorly, or fails to make it at the right time, he can suffer far more than a momentary rebuff, and be discarded as immature, or too violent or too weird, and so on. If the female performs her rebuff the wrong way, or fails to rebuff at all, depending on the exact guy, his life stage, and the circumstances (it’s all VERY interactive), then she might be discarded for similar complex and varied reasons.
The appearance of hypocrisy about it all, is not actually inherent to the process, but it is common, because very few people actually understand the overall process they are participating in, so they do it all crudely and clumsily. Rather like a lot of human action, really.
It’s not as simple as is commonly portrayed in discussions like this.
