Questions: Girl's Behavior

I check her out til she notices I am

As we know, most women find the vast majority of men physically unattractive due to not being born with physical traits out of their control. These traits include, race, height, skeletal frame, early male pattern baldness, hair colour etc. We also know that women in their prime tend to hyperfocus and date the hottest and/or richest men and often use sex to try to secure a relationship. Granted, some women are smart enough to lock on an average guy, who shows high potential to be a successful earner and gets him to commit to her early.

Now, for the men who this doesn't apply to, they are basically told by women to "work on themselves", which basically means to grind and make tons of money, so when women are ready to settle down (usually by their late 20s to early 30s), they have a nice retirement plan to look forward to. Women will use the fact that this group of men are sexually/romantically inexperience, as well as, desperate to reel them into commitment. Sex starts off enthusiastic to hook the man in to the relationship. Women are also on their best behavior and guys are lead to believe that this will be the baseline more or less.

Eventually, when an average man marries a woman, another layer of security is put in place that basically ensures the man pays a hefty price if he ever leaves the woman. This is usually in the form of spousal support an/or child support. Thus, women no longer need to have sex with you, since she has you shackled to a contract that says you provide for her in or out of the relationship. Sex is used as a reward for good behavior/out of duty and not because the wife generally wants to sleep with their husband. Sometimes, women will stop sleeping with their husband all together, despite his best efforts, and men feeling neglected often seek sexual relief else where.

Example, this sex therapist is able to make 500k/year by sleeping with men whose wives have stopped sleeping with them.
