My nurse suggested this when I wasn't contacting and it totally worked. It's just like it sounds, no need to be rough about it ;)
If done in the correct way it can bring on labour. I think you body has to be getting ready for it too. Theres different techniques. If you google it it will show you the ways to do it. Many women has had success using this method. Give it a go. :-)
Thanks but sex is out of the question. When I think about it I feel sick..
I would assume pinching and squeezing them. If you are trying to speed along labor they say that sex is the best way. Also walking and walking up and down stairs
