Best wishes, the biggest thing IMO you can do for your son is make sure he can trust to talk to you about everything.
He is going to interact with guys that are highly toxic and damaged in his life and will do so. It will be more than just about his interactions with women. It in some cases will be a fight for his integrity and ability to keep boundaries and be self confident and safe in his own space.
If women have an innate natural fear of men, you should see how it devolves when it is just guys around. I have no doubt there are groups of women that are brutal to one another in private as the human condition can be similar across the board), but from my experience the guy v guy would take women's breath away.
It is why if you see a non-feminist man state, you want me to treat you equally as a man and laugh to a woman's face, they are remembering the whole situation of man.
One humiliating experience can undo a lot of parental training.
If one treats marriage and birth rates as canary in a coal mine, one can track how bad the "gender" wars have become. It should not be like this, and it will get worse given college rates for women now are 60% to 40% which is rates equivalent to those of the 1950s with role reversal. If we treat those times as toxic gender wise, ugh. This will not be pretty.
So your work is very important since the more normal feminist oriented guys there are make it easier to help us smooth over the others ...
On the respect front, I read that college educators were concerned that once the ratio went about 55/45% that the sexual dynamics shifted where the more alpha/traditional masculinity. The premise was the top 80% of a gender always fights for the top 20%, and things slide, and people will drop standards just to not be lonely and "mate".
In this environment, boys get tempted for the forbidden fruit since it is right there for the taking.
Be well.
