My greatest satisfaction is my wifes satisfaction. But think about this. Sex with the same person everyday can get kind of predictable. What is it like the first time with anyone though? The passion and excitement is usually taken up a few notches. Given my familiarity with my wife I know exactly what she is going through. I know what every moan, every scream, every arching back, every heavy breath means. Now when she is with another, it’s like another first time for her. I know exactly what she is going through but with much more intensity. The moans and screams are elevated a few notches. And when I see those nails dig in and her legs wrap tight, well, her satisfaction is my satisfaction. And if someone can do it better than me, all the better.
