It's time to face reality and say farewell!

My wife and I are good friends but if we lived together I am sure we would be divorced. We just had our 23rd anniversary.[/QUOTE]You are 'good friends', not living together. Why are you afraid that she might see your scratches on your back?
Is this relationship still more intimate than you admit to yourself? You don't help your wife to make a new start in life, when you don't know for yourself what kind of relationship you wish to have for your future life. The scratches are not the problem, they are just a symptom of your screwed up sexual life traveling around the FKK scene. As is your wife's overweight. You might think about a consensual divorce, making space for a start into new real-life relationship. This fucking around in the scene means avoiding a sexual activity embedded in a love relationship. I wish you all happiness for your future life!
