What age do you guys find cuddling to be inappropriat?

Despiona
There's this 12 almost 13 year old boy who is constantly trying to cuddle my husband when we're around. He rubs my husbands muscles and try's to cuddle in bed with him. I find this extremely strange and inappropriate. 
Edit: my husband is not this kids dad if anything they are second cousins. My husband is 21 and this kid is about to be 13
