TMI: Stimulate Nipples?

Amanda

So I had my 38 week appointment today. Baby is in position, cervix is dialated and I'm thinning out. Doctor said I should keep walking, have sex and stimulate my nipples to get labor going. I know how to do 2 of the 3 really well. How/what do you do to stimulate your nipples? Just rub them? Flick them? Hubby nibble them? Most random question I've ever asked!
