Sending me into labor?

Might be a dumb question just curios. Is it true that having you boyfriend play and suck in your nipples can make you go into labor? As well as orgasming and having him cum in you softens your cervix and can also send you into labor? Like after he cums in me I get a bunch of light contractions and someone told me these things.
