Can sex help induce labor even if he don't cum in me? I'm 39weeks 3days pregnant and we had sex today odd because he hasn't wanted to touch me because he thinks hell hurt the baby lol but any ways he didn't cut in me he pulled out and did it on my ass. Can having sex help? I was dilated to 1.5-2cm and 60%. That was last week I have my last appointment tomorrow morning and I'm hoping for great news!!!
