i bought myself a pair of supple nipps 3 years ago from nipplefunwear and still use them 2 or 3 times/week mostly after breast massage. sometimes, in a warm bath. i like them. they do work. my areolas are not small and my thinking was that larger nipples would make them happy. i was worried at first, i think it was only the 3rd time i used them and i left them on for 2 hrs. i shouldn't have because i guess my nipples were just not ready for it and when i took them off, there was a tannish liquid inside the cups and in the left one, a tiny bit of mucus sac or something like that and under a loop i could see a tiny speck of red, probably blood. it kinda freaked me out so after that i kept them on for only short periods. 15-20 minutes. now, 3 yrs later, my nipples are much larger and i can keep the supple nipps on for much longer without any problem. if you do start using them, you'll notice after a session your nipples slowly get back to the size you remember but over time, they do get larger. i don't know why, maybe i'm a nipple freak. i just like larger nipples.
