DS is 14 and neuro divergent. He's quite immature for his age, and is like a younger child in his manner. I usually hear him talk to his friend about games, but last night I overheard him say to his friend on the phone "How many times did your dick go hard whilst you were talking to her?" I was a bit shocked to hear him talking to his friend like that, so I told him to say bye to his friend. It was time for his screens to go off any way, and I take his technology every night and lock it away. He seemed a bit mortified that I'd heard him say that, and cleaned his teeth and went straight to bed. He usually faffs around for an hour after screens off. I told him not to ask his friend that. A little while later, I went into his room to talk about misogyny. He didn't know what it was. I told him it's treating women and girls badly, and I said that girls aren't objects. He was embarrassed and just wanted to go to sleep. He was turned away and didn't want to talk. I thought it was important to say something.
Is this just a normal thing for teenage boys to say to their mates? I don't want him to feel shame about normal feelings of being attracted to the opposite sex, and erections. But I also want to protect girls from this attitude from boys. How do I manage this going forward? I'm planning on having more little conversations about misogyny now and then. Does anyone please have any experience with this?
