Nipple Torture
How much pain can you tolerate in nipple torture?

Men: do you like your nipples being played with?
I personally have little sensation in my nipples and don't care for nipple play, but my partner is very sensitive and he loves when I play with him...

I have pierced nipples!!! . . . Do you?
I'm just curious who out there has blinging titties. I have them, love them, and think they're a great look for alot of people. What's your stance?

nipple clamps?
i'm thinkin about getting some, any ideas on what's best? or are they all pretty much similar? and just depends on the style you like?

How do you use nipple erectors?
so i have been seeing these nipple erectors? how would you use them, is it just my mind or are there rubber bands that go on your nipples too?

Mine are pretty sensitive. the only time they can be touched is if I am aroused, otherwise I hate it.

Fortunately they aren't overly sensitive, but on the other hand I would prefer them to be more sensitive. I think breastfeeding for around 4 total years made my nipples less sensitive.

I'm not aware that mine are that sensitive.

My wife's nipples are not overly sensitive - but just before her period, her breasts are sensitive from the water build up. It resolves in a few days - and is not as bad it use to be, her progesterone cream helps limit the discomfort.
