Think about it.

A very conventionally attractive guy: Over 6 feet tall, lean athletic build, great face card and perfect toothpaste smile, with ... let's say average to over average social skills will not have a dearth of female attention.

To him he has always got girls fall for him, or at least agree to go on a date enthusiastically so he probably feels "being himself " works.

And unless he is a late bloomer, i.e gained all this attractiveness later in life due to weight loss or belated glow up, there's no reason for him to be bitter towards women.

In some cases, if he has a huge group of friends, he may notice how women treat his lesser attractive buddies. But unless he comes across that, he will really have no reason to look at women with suspicion and cynicism.
