Finally had the birds and bees talk - went better than expected

My 12yo boy asked some serious questions about relationships and intimacy. I was nervous but remembered that God created sex and it's not dirty, it's holy within marriage. Focused on teaching him respect, that this is between a husband and wife, and that his body is a temple. He seemed relieved to talk to me about it instead of getting garbage information from friends. Prayer beforehand really helped me stay calm and biblical.
