some info first. My son had a typical behavior till 2-3 years ago. Then he stopped going to basketball training, stopped seeing friends and started to close to himself. He has hypothyroid problem so he takes T4. As far as his behavioral image is concerned, he rarely talks about girls or looks at girls (although maybe 14 is a good age to start doing so). Moreover he never exhibited any of the classic gay symptoms (basically he never showed anything that would make us believe he is trying to be the opposite sex).
Lately for some months now we notice he spends too much time in the bathroom. Not knowing what is happening in there, we put a hidden cam, and to my surprise this is what we found :
He masturbates while looking back at the in-wall flush's cover which acts like a (somewhat distorted) mirror.
So we concluded he is looking at a somewhat distorted image of his back. His face does not seem like he is enjoying it, he seems like he is doing it out of "duty" or anything.
As a history record, my wife's brother, without being at all gay, he never showed any interest in women, so he is still single.
I am deeply concerned about my son.
What is this? Does it have a name? Will my son be normal, eventually? And if not what can I do? Hormone therapy of some kind?
I have never dared to talk to him as he will get angry and maybe violent.
