Marriage was a bill of sale between father and new husband. It's antiquated and likely causing more harm than good at this point.

I think you've missed the point of my article. You aren't "entitled" to anything. If she isn't willingly giving you sex then you have the three options as I spelled out.

This is the part people get stuck on. Because they want the other aspects of the relationship, so they don't want to leave the whole relationship, they simply want their wife to put out.

But the reality is you can't force another human to give you something they aren't willingly giving you.

The only behavior you have control over is your own. Don't like what your partner is or is not providing? Then you can learn to deal with it, you can compromise, or you can leave. You cannot force them to give you anything, including sex and monogamy.

And yes, plenty of men aren't putting out in relationships for one reason or another. bodily autonomy knows no gender.
