Without getting overly involved in mechanics, first you seem genuinely concerned that your're being honest with yourself, that's a plus. Biologically, and look at other species too, males like to be engaged sexually, we're simply not "programmed" for monogamy. Committing oneself to being sexually exclusive is a choice, and one that can take some effort; albeit not invaluable effort.
While some folks might poo-poo the choices my husband and I have made, we're much more fluid about sex. Where we aren't fluid is in our commitment of our lives and hearts to one another. If he wants to suck a dick on his lunch hour, he can have at it. Reciprocally, if I want to get sucked, or pound some willing fella's hole, as long as we're responsible and safe, no problems. Sometimes we play together with a third, fourth, or more. What we have discovered is that in exploring our sexuality and our honest attractions this way has actually led to our having even more amazing sex with each other. We always had a great sex life, but didn't try to fool ourselves that there were still other sexually attractive men in the world.
We discussed it over time, and came to agreeable terms. For us, home comes first, no spending hours on a hook up app when we could be having fun ourselves, be it sexually, or going for a hike, walking the greenway, challenging each other in video games, bowling, roadtrips, and dancing. We're not off boinking daily or even weekly, but we're more concerned with the concept of intentional denial in order to meet that aforementioned bill of goods.
I hope you and yours have an amazingly love filled relationship. May it be filled with honesty, and lots of good fucking, however that works.
