We started talking with our kids about sexuality when they were 3-4 years old. Recently, I discovered that my 15 year old son was hiding away some gay porn magazines under his mattress. It reminded me that he talks much more about boys than girls, which made me wonder if he's not interested in girls at all. He has some very good friends who are all boys. I know it's normal for boys to hang out with other boys at this age, but he has never talked about girls in an intense, curious way like other boys do. Should I consider the possibility that he might be gay? How should I be a supportive parent if he is?
