Men can lactate, specifically when they are severely malnourished, but I have heard it's possible to induce it in various ways. This would aid the survival of a tribe when food was scarce by keeping the babies alive for longer, but some mammals can do it under normal circumstances as well.

I'm standing in front of my coffee shirtless pushing as hard as I can and it's not working. 🤯

It generally takes months. It's not like women can lactate just by pushing their nipples either.

In the ordinary course of events, they need to get pregnant, build up all the ducts and milk producing cells, and then get the right combination of hormones to trigger milk production. And then you have to keep removing that milk, or it stops.

You can get people not going through pregnancy to lactate by giving them the hormones. Recovery from famine can also produce the needed hormone spike.

Because in the womb,the person develops with both genders,then settles on one(why women have a clitoris,it would have became a penis). Men kept the nipples when they developed male. As George Carlin put it"congratulations guys,you're a biological afterthought." (Also I am not a doctor/biologist,and that is a stupid simple breakdown of development. The Carlin quote is accurate-ish,though.)
