Locked forum categories to protect childs

Hi, I’m creating a forum for people who wants to talk, meet each other, become friends, fall in love or get informations about associations. I would like that the members of my forum who have less than a specific age can not be able to access some categories of the forum. Can you add a switch in the categories options so childs or are not able to enter in it, based on the birth date they entered in their account? Thanks.
