This is typical middle-man crisis.
You have a decent family life and you are longing for more sexual excitment to satisfy your quest for youth. You want those wide sex, you want the tight legs , you want those pink nipples and pussy lips, you want those perky tits...... all these you have never have the chance to pursuit when you are young. Now you have the $$$ and the time, you want to find the excitment of your life. Cheating on your wife seems fine and reasonable with your own logic. That's exactly why many bald headed middle age guys driving bright yellow open convertible sport cars. They want to tell the world that they are still young and energenic even they know their little dick may not work as they hope for. Here comes the Erectile medicine-Viagra, cialis, etc.
I more or less in the same boat but I am not inmmue to sinking but I set the rule to only make friend with MM. not close girl friend relationship. I have been back to China for last 6-7 years now and more I play, the more realize the golden rule Iset is the correct one. I am not here in China all the time and can't afford to keep one for privatization. I will be a fool to think the girl will stay true to me all those time I am not around. This is business for them, they only have the young body and face for short period of their life and they need to make the best out of it. So all know it is all of game only but some guys think differently. Tjhey really think the girls are falling for them. Come-on be real. Even if the girl really likes you, can you afford to keep her for good??? what you find another one ven better than her later on, would you dump her???? vice versa, if they don't feel secure enough with you through tieing the knots, they will jump ship too. IT IS ALL JUST A GAME FOR ADULT. play it, enjoy it while you can.
Like the Steve Miller band say; I am a looker, i'm a lover, I'm a deamer, I'm a joker..........
