I could get on a huge soapbox here. John Eldredge wrote a few books on this topic, I encourage anyone with male children read some of his books.
I’ve found John Eldredge’s books very informative and helpful. Also (with reservations), Michael Gurian’s books.
The girls in my 8 year old grandson’s class are crazy about him because they say he’s one of the only boys that is nice to them. On the first day of school, one of his classmates was in total meltdown. The principal was walking her to the classroom while she cried. My grandson walked up to her and told her that they were in the same class this year and everything would be just fine. The principal thanked him for being so kind to her and the next day summoned him to her office where she gave him a sticker for his kindness. I was very happy to hear that he was acknowledged for being thoughtful.
Here's what I tell my nephew that sums it up fairly well:
I signed my son up for Boy Scouts to get him around boys and the leaders are all women. He is 6 yrs old and a parent has to be present at all times which will be me, his mom. At the first meeting the mom in charge is trying to get the boys to sit down, be nice, stop rough housing. o_O
