HI & Welcome to the forum!!!!!!!!!!!!!
I have just started to use the nipple cups,
and have found them to lengthen the nipples,
and enhance the feeling in them. Not noticing
any noticable growth in width.
With the inserts in place, it limits the amount of
tissue that can go into them at any one time.
Now if you decide to remove the inserts, the area
is a lot more open, so more tissue can go into them,
and result in substancial growth of the nipple.
I hope this helps to explain it for you. Send Lucy
an E-mail for further information.
Stay safe and have fun!!!!!!!!!!!
