Women are simple to manipulate
This comes from women's emotional nature, and also very often explain their draw towards the spiritual.
As men we are predatory by nature, and driven by lust. We are thrilled by the chase of women, as something we can catch and have, penetrate, sodomize and dominate!
Most of what you regard as "chemestry", "vibe" is all seductive manipulation games to penetrate you.
The brutal truth here, is that we men play dark and manipulative games to get access to your body. And this does by no means help you, as society is pushing the social construct of
"the sexual revolution", that have worked in women's favour in no other way than serving them as prey for men.
Stay away from alcohol
Alcohol seduces women, it messes with your brain. As the saying goes "Alcohol makes her legs open". As such you want to avoid men that are into the party/drinking life.
A bar or a club is not really different from a brothel, the only difference is that a man is not guaranteed to penetrate something. But as a woman you are still the product.
You want him to chase
The harder you are to get, and have been to get. The more of a price you are. This is true before and after a relationship have started.
In the relationship you also want him to work hard to get access to your body, if you remove the chase, the "hunt", he will die a little bit inside. And this is the major reason why men cheat on women.
In other words, you want to feed his predatory thrill of the hunt!
