My 14 year old is in a relationship with an older girl of 16. He's tall for his age and looks the same age as her. He also acts old for his age, so their relationship doesn't look odd IFSIM.
But, the fact remains, he's only 14 and she's more experienced and emotionally mature than him. It's his first relationship.
They don't seem to actually meet that much out of school, a lot of their relationship is online. It's early days, however, maybe that'll change.
I don't know her at all - she's been around a few times, seemed nice enough, but didn't say much when I was there.
What should I be advising him (other than the obvious staying safe talk, he's had ages ago). This is totally new territory for us.
