What age did you start becoming sexually aware?

I am a single mum to a 9 year old. He currently is (to my knowledge) very naive. He doesn’t swear, he doesn’t have a console (coming this xmas) so he doesn’t speak to his friends outside of school. He has never known me to have a boyfriend. I just want to be prepared for the years when he starts becoming sexually aware. Is it way too early now? What can I do without a man around to have this discussion. Is it a case of shut the door and give him privacy (he always walks around naked and sees no issue in this currently) or should I start talking about his body changing soon. I just want to make sure I do it right and don’t **** him up forever
EDIT: thank you for all your comments. This has been very enlightening. I am shocked at how young most of the comments are. I fully expected it to be around the 11/12 mark. However, I feel much more prepared now than I did previously. Some excellent advise received. I am also sorry to anyone this triggered, I’ve read some sad stories and I did not mean to bring this up for you. I am sorry that happened to you and I hope things are better now, I thank you for sharing though. X
