When I was a kid, my mom sat me down and said “You know, Sven, if you are a lesbian it doesn’t matter to me one bit” and left it at that. I was mortified- just because I was unpopular didn’t mean I was a lesbian. But if I had turned out to be gay, I would have let her know and I’m sure that talk would have saved a lot of anguish.
I wouldn’t worry too much about the kids at school. It’s very different now than it was even just a few years ago, and there are plenty of “out” kids in schools.
It sounds to me like he might be transgendered. This means the gender inside your head is not lined up with the gender expressed in your body. Generally people know this from a very young age.
There are four places gender can be expressed- physically, in hormones, in actions, and in the head. Any one of these can get misaligned. In the end, it’s the “head gender” that wins. While bodies and hormones can be changed, there is no force in the world that can change “head gender”. No amount of counciling or hormones or training can change this. It’s real.
Unfortunately, this misalignment can cause a lot of grief. Imagine waking up tomorrow in the body of an old Chinese man. You’d be weirded out. You probably eventually come to hate it. And you’d do anything to have your body make sense again- especially if people insisted on treating you like an old Chinese man. Most transgendered people have a desire to make their physical body match up with their real gender- the one they believe. Solutions range from buying pink dress shirts to full-on surgery- each person knows what is right for them. Most people also take hormones for their right gender. Their body isn’t making the hormones they need, but luckily with science they can get them.
Transgendered people can be either gay or straight. It may seem insurmountable, but it’s actually pretty possible to live a normal life with a spouse, etc. Love seems to be stronger than gender. But it’s still much less socially acceptable than being gay. It’s a lot for people to wrap their heads around. But love and acceptance go a long ways.
If your son is transgendered, he will probably know it by now. Unfortunately as the body ages, it can be harder to “transition” successfully- if the body gets the wrong hormones at puberty and through the teen years changes happen that can’t easily be reversed. If he does come out to you as transgendered, it will be important to talk to a doctor about it. They may advice some hormones, etc. in the teen years. This may seem too soon, but physically it can be important.
