Why do men I’ve worked with several years ago, suddenly add me on Facebook and want to re-connect?

Seems strange that it’s always only men that I haven’t seen for several years and didn’t know that well, suddenly add me on Facebook.

Or it’s an old friends with benefits that just fizzled out, I moved on but he keeps trying to contact me in strange ways?

or a guy I had sex with once then distanced myself from or just lost interest.

or just a random co-worker…

seems like men struggle to move on or maybe feel the need to re-connect or reach out? It’s almost never female co-workers doing this, always men.
is it because they want sex or feel attracted to me? Or just to be nosey?
