Yes they do

What have you done!? *struggles to hold the pervs at bay* 🤣

I haven't noticed mine changing honestly.

Mine also change from stimulations . Like different clothing materials have an affect .
Polyester is a no no for me 😂

Mine definitely do 🤣🤣

Mine do when it's cold, I haven't paid attention to the arousal thing though. I wonder if that part can happen in men.

They change. I haven't paid enough attention to figure out what causes it, but now I'm curious... in the name of science. *grabs a pen and notepad*

Mine change, and wife's change, although mine are more sensitive.

I don't pay that much attention to them. 😅 I just noticed they get really soft and flat in hot weather.

. Mine do. In my experience ladies change much more

Mine do and they change colors a bit too, especially my nipple. It is darker when hard.

I just grew an extra one. Does that count?

Mine definitely do !!

They do. Mine don't change color but they are sometimes smooth and other times tight.

Mine will grow on ya 😉🤭

Mine do

Sometimes my areola is smooth and flat, and pink, then when colder it shrivels up small and goes a bit darker, tight but no longer smooth

My nipples definately get darker when hard and aroused.
Women's nipples are just 🤌
