I get the feeling that the USA is very different to other parts of the world. I know SOME women who cheat often and act like this, but I know tons who aren't.
I will repeat my oft-said mantra that what we define as "hot women" is something self-constructed by the lady herself.
A woman who spends all her time in the gym, trying to look good, is the type of woman who will be looking for c0ck at every turn.
A man who spends his life bodybuilding and building overtly masculine traits, is the same. Will women find fidelity from such a man. Unlikely. They may be thinking he's a "hot guy" but we all know, that shyt doesn't fall from the sky. At some point, that guy decided to dedicate hours of his life to building muscle, building a frame and a life which attracts women as a priority. Over say, studying something, learning an instrument, or another interest. So this man is much more likely to screw around - that is what was the driver for choosing this lifestyle. No different for "hot girls".
Adjust to different women and you'll find the loyal ones there. Strippers, instagram girls, regardless of how secure they seem, are still living life very much for male attention. The very thing which draws you in is the poison which destroys you.
Just my 2 pennies worth.
