Whats the correct ways for nipple stimulation and have you done it if so share?

ur suppose to pull and rub ur nipple and rub the dark part around ur nipple kinda like messaging it u could also use a breast pump u can do like 15 min on one nipple then take a break for 15 min and do 15 min on the other nipple/breast and 15 off and then start the routine all over again so 15 on 15 off for an hour its best to do it every couple hours or 3 times a day but good luck I've been doing ns for 2 days and nothing has happen yet but w work i can't keep doing it but if u can keep doing its it could work for some ppl it does work. just be carefull doing it so they dont get so sore and tht its can causr long and painfull cobtractions let me know if it works out for u
