It’s stuck in my head, what exactly happens when your nipple goes hard? And does it happen to dead people when you touch their nipples?
I know about the d**k that it can stand up or whatever

When you touch a nipple, blood flows to the area and muscles contract, pushing the nipple out. Much the same as an erection. Why? A few reasons, if a nipple is being touched, there’s a chance its for breastfeeding, so it becoming hard helps, or its due to sexual arousal, and the same thing applies. Cold can also cause them to go hard, this is due to muclscles contracting to lessen heat loss.
