DS is 12 and has had the same girlfriend for 3 years (also 12yo). They were friends before they became 'an item'.
The thing is, they have always had sleepovers at each others houses, where they share a room. Last time they slept here was about 3 months ago. She had a separate bed in his room, as usual, but when I checked on them, they were in the same bed with their arms around each other.
I have spoken to DS about it and told him they can't share a bed, but now I'm thinking that actually, they should not have sleepovers because I can't 'police' them all night.
I know they are very young, they have both said they're not going to 'do anything' but they do kiss on the lips and say they love each other. DS's girlfriend has told me that he 'dared' her to 'snog' him 
AIBU to say 'no' to sleepovers?
