After birth...

I know you are supposed to wait a certain amount of time for sex after birth... Does your doctor go over all of this after you give birth or before am I supposed to just Google this information ? First time pregnancy. And secondly is it ok for clitoral stimulation within that time period of not having sex? I'm just curious. I'm 6 months now so who knows how things are after you give birth.. Just need some info ladies if anyone can help !
