I'm white, married, don't cheat on my wife, never have.
My wife is good looking, dresses nice with a warm smile. I like to think I'm similar to her.
I've had nice warm conversations with good looking intelligent women at Starbucks and the grocery story. I like to think I could nail one sometimes, I'm sure I could but I never let it get close like that. I've had gals tell me they'll be here(Starbucks) tomorrow, next Friday, next week etc. I don't tell my wife any of this. I'm sure she gets hit on way more than I do.
My advice..be warm, genuine and friendly. Invite her to coffee nearby. She just might say yes.
...a few years ago we were at a neighborhood party at someone's home. A very good looking wife quietly told me she'd be very interested and my wife would never have to know. I was shocked beyond belief and politely declined but I felt so damn good.
