I’m wide awake in bed right now unable to switch off and sleep 
DS is recently 15 and his girlfriend is recently 14. They’ve been together for about 5 months. Naively we and her parents have trusted them to go out and about together and not to be getting up to any funny business - we’ve always explained it’s best to wait, especially with the years gap between them that it’d be illegal, etc. It has recently come to our attention that they have done all but full sex (supposedly), and have found ways to sneak off from public view to do this
. I am shocked and heartbroken that this has happened. The girlfriends parents do not want any further contact between them unless it’s chaperoned and that if this means they have to see each other less, so be it. I am concerned that this restriction will make them more likely to go secret and continue with/progress on shenanigans on the other hand I want to lock DS up until he’s 18. We’ve always talked to him about consent, safe sex, condoms and where to get them but this doesn’t relieve any of my anxieties around this whole thing 
Any advice??
