Ugh this is such a weird one.
I'm very happily married, love my husband, no intention of leaving him. His boys are mostly sweet but sometimes very touchy feely. The older one, who is six, looked down my top down and sneakily sometimes tries to touch me. I move away immediately and shout "No! That's private!' One time he said 'oh why can I never touch girls?' Which was a bit weird. Their gran says he does the same to her. Their dad is horrified and reiterates that it's private as does their gran but they still do it. Advice pls.
