I hate being dishonest. I love my wife, she loves me. Everything is great. But, the fact of the matter is, she isn't 20-something with fake tits and she never will be and that is my greatest turn-on.
I restrict myself to going to an MPA to ONLY when she is out of town... which is rare. This also helps my wallet... as this hobby needs to be infrequent! This way, I am only lying by omission. I never lie about where I'm going or what I'm doing.
