When I was a teenager I once baby sat a couple of 6 and 7 year old boys of a divorced Mother. Both of them - the younger one especially - kept wanting to hug and kiss me and (I kid you not!) rub themselves against me! They told me that their Mom would bring men home and they would listen outside her bedroom door.
I finally had to get my own Mom to come and take care of them cause it was it was more than I could handle.
You did the right thing.
