Intensity of Passion (TMI?)

I'm 36 weeks and my SO and I have been very busy in the bedroom. Sometimes certain positions hurt... Like I can feel him jabbing into my cervix (at least thats what I think it is) but other times the same position can feel good. I'm wondering can the intensity of our "bedroom sessions" have different effects as far as inducing labor? Like if we are more rough will it send me into labor easier than if we are gentle and easy? I'm wondering because earlier today I mentioned that I'm so ready for this baby to come and he jokingly said "well if ya want I can give it to ya hard tonight"... It got me thinking.
