For context, had the talk about the age of consent and consent issues, other stuff that could go wrong- break-ups, not sharing pics, disease, pregnancy, reputation etc. They’re a few months into a what seems a happy relationship, same age.
We don’t have a weird parent/child situation just quite honest with two teens in the house and I’m thinking along the lines of ‘if you were to decide it was the right thing for you, I’d want you to be responsible’.
