In all honesty, I really don't think the sort of people who would need this sort of information will have many friends anyway.
Think about it. What he's worried about is, will this persona be any good in bed. In other words, he's taking someone out for sex. He's treating women like prostitutes, he pays them with dinner and expects his reward. But he want to be sure he's going to get the right reward.
There are a lot of men who think this way. But how many women want to be treated in this way?
Imagine a genetic female. She has her flaws and like every woman since the dawn of time, she know what they are and does her best to work past them. Then her date is examining her for any flaws. Like he's buying a dog, or a horse, or a second hand car.
I recall, when I was still at school. Every boy, (12 years old onwards), claimed to have bedded dozens of women. Information was exchanged on how to spot the best ones. If she's too friendly, that means she's desperate. You can alwasy tell a virgin because they walk with their knees apart. If a woman blows cigarette smoke in your face, that means she's interested in you.
The first time I got near any chance with a girl I was 17. After 5 years of the usual school boy nonsense. She lay down on the grass with her feet about 12 inches apart, fully clothed. I flopped down onto her, put my knees outside of hers and pulled her legs together. I really thought that was how I was suppose to act.
Someone once gave me a maxim about relationship that sums it up nicely.
It's to be experienced rather than discussed.
