Nipples!

Hi, got this friend that has inverted nipples and really doesnt feel bad about them, but I'm like wondering what the advantages or disadvantages are in having them. Are they very sensitive? not sensitive? Any research showing if the owner would be more sexually active or less? Read a bit about how to correct them but she's not particular about correcting them anyway. let me hear from you; principally because she wants to know.

thats funny

if you really don't care then why would you post it on here? It shouldn't matter!
