Nothing you do will send you into labour unless your body is ready to labour basically.

Nipple/clitoral stimulation, hot curries, long walks and bumpy roads... pmsl All the same boat.

ETA: the sexual arousal things all release oxytocin, which is a major hormonal driver for labour. Hence why sex in early labour can be amazing and incredibly helpful. It also causes engorgement of the vagina, which increases the size of your birth canal (by up a good 2 cm ) and sends more blood to the uterus assisting with contractions efficacy.



Now if he was sucking vindaloo off your nipples while using a Rabbit, driving down a bumpy road after you drank castor oil.... I cannot be held responsible for the outcome...
