I was a total “tomboy” as a kid — just preferred “boy” things — sports, toys, clothes, etc. But other than the occasional throw down about clothing (wearing a dress on Easter, etc.) and actually being mistaken for a boy (which even I realized was fair enough, that’s how I looked), I really don’t recall ever being given a hard time, in any way, neither by family, friends or strangers. Granted, that was 30-odd years ago, but I think it’s still true to this day that it’s far easier for a little girl who is drawn to “boy” activities / toys / clothes than vice versa, and that really is an awful reflection on our society. Kudos to you for supporting your son’s choices and and not freaking out about what that means for him as an adult — because you don’t have to, since you’re giving him such a great foundation of self-esteem right now.
