Grade 1 nipples will maintain protrusion without retracting. These nipples protrude a few millimeters from the areola at their regular state, but protrude further upon arousal, temperature changes, or tactile stimulation. But once they realized it was for "research" and a report for the OG, most obliged. It took me forever to call each of them or their husbands and get that info. Grade 2 These nipples can be pulled out—though not as easily—through the same manipulation method as Grade 1 nipples. TheAlchemist - In for knowledge Lots of studying to be done for sure!

It took me forever to call each of them or their husbands and get that info. Puffy Puffy nipples have most of the same characteristics of "flat" nipples, the only difference being that in "puffy" nipples, the areola is raised up off the breast. Flat nipples are not everted at their normal state. The milk ducts tend to be constricted, rendering breastfeeding impossible.
