some times its the person dealing with hormones but if its cold out side or the person is cold the nipples get or it can be from being horny. ask your parents kids : /
Everyone is different. When you are young your nipples may be hard a lot of the time. As you get older your nipples tend to become hard only when you are cold, wet or sexually aroused.
Because you're horny?
It means you're horny or have chills.
Sexual stimulation is one way, and another would be that she is cold.
I'm in your boat too and I hope you get an answer
you can either lose or gain sensitivity; your nipples may or may not be hard all the time; they may get a little darker, just the nipple part. and some people are really different, so it can go anyway at all, really.
It all depends on the way your nipples were made!some are squished in and some are pointy!if your nipples are pointy it doesn't matter if they're squished in that's fine too!
Not all male mammals have nipples. I believe mice, rats, and horses are examples of mammals where the males do not have nipples. In fact, the platypus is a mammal, but it has pores and no nipples. Why this is, I do not know. I am trying to find out, but the information seems to be hard to come by.
It's from all the dirt that goes in there.After 2 days,it gets all crusty,yellow,and hard.
That happens to me all the time! The best way to make it stop is if you gently rub a little bit of lotion on the nipple. I hope i helped :) !

Yes, all female raccoons have nipples.
