It's not Mr. Non-Commitment any more.
80% of women on dating apps find only 20% of men acceptable.
If you are a man in that 20%, you will discover that women only want you to get their panties off (to start), and for a very substantial fraction of that 20%, that's an OK way to live.
For a woman sharing a man with four others (80-20, remember), that becomes the very definition of "senseless" at some point, but by then, again if you are a man in the top 20%, the replacement supply (since you can date down 15+ years) is nearly endless.
