I've noticed married men on average get more women than non-married men.
I have my theory abt why is this:
first of all the social statues: being marreid elevates your social statues bc it means you were chosen/ desired by a woman, which in turn means you're desirable. Everyone trusts women to choose a responsible/mature man to settle with. So even if he actually isn't any of these things, his wife approval makes it look like it.
Being married makes you look like you have your sh*t toegther. Being married with kids is everyone's idea of normalcy and stability. For society by and large, you can't live a fulfilling life without these two.

Without getting too deep into spirituality. The married man also has the female energy of his wife all over him, which attracts women like honey with bees. (He has a good balance of masculine vs feminine energy.)
I noticed personally that guys who are already married or in commited relationships don't have the same needy/clingy energy as single men. Their needs are already being met so they don't come off as desperate like the other guys, who get attached super quickly and want to be babied.
