If he suddenly really wants to do his laundry one morning, don’t ask questions. (Wet dreams and embarassment being the context here.)

That’s about all I can think of that’s gendered, really.

I was ~9 when I got the talk from my Dad, and it was basic stuff about just the mechanics. It set things up so that, around 13, I went to him with questions about how I was feeling re: puberty. So even now it’ll be helpful to do the talk and show that you’re available as a resource.

In your case, your son likely has some idea from internet pornography and whatever he got in school, but it would still be helpful to go through the basics with him. I’d frame it as “I’m sure you know most of this, but i just want to make sure you know what’s important.” It might also be helpful to make clear that pornography is as much acting as TV is - don’t set his expectations on it, it’s people faking things for money.

Going over the importance of condom use also helpful at his age. Keep in mind, it’s not necessarily about what he’s going to use right away, but making sure he knows when he does need to know.

Then, I’d just be there for him and ask if he has any questions, and answer them frankly. Tell him he can come back later if he’s unsure.

It’s awkward and tough I’m sure, but it’ll be a help not just now, but going forward. Good luck!
