One of the things we HDs do when we try to reason out our spouse's lack of interest in sex is to think "s/he must be having an affair!" After all, that's the way we think. Why else wouldn't someone want sex all the time? Because they're getting it elsewhere. Not true, of course, as SSM tells us.
My question is: Do you LDs ever find yourself desiring, or even following through with, having an EA or PA? Or is whatever sexual energy you have always directed at your spouse?
