I work away from the city I live in. I go months without seeing my wife, so this is how I justify it. But I also look at it this way: So many men have affairs, and break up their marriage, and sometimes that of their married partner. Kid are hurt, homes are lost, etc. I don't get people who have an affair with work partners, a neighbor, or their wife's relative (it happens). It will never end well. If you have an urge to "cheat", this is the way to do it. Hopefully no one finds out, and no one is harmed. None of these girls are going to fall in love with us, and show up at our door, or call our wives. So really, you are saving your marriage, not destroying it. lol...how's that for justification ha
As far as the sex decline after marriage I would think that would happen in any long term relationship unless you really work at it. Like everything in life it seems like a cycle. We are animals and probably feel that crazy lust in the beginning so we procreate. After that it makes sense that men would look else where to spread their seed. I am okay having sex with my wife once a month or none at all. I dont want to eat her pussy and Idc if she ever blows me again. Most of the time I look at it as work and I would rather jerk off. My point of view on marriage overall is that we are partners now in something much bigger than sex. Our family is a company we need to run well.
But not enough emphasis can be put on the fact that having this hobby as an option is an absolute necessity. A long term monogamous relationship just seems impossible in my mind for men.
