When I was a teen I did wonder what they were..... but like many here, I hadn't a single person to talk to or had ever explained anything to me... so I figured, if it wasn't normal sooner or later it would get worse and maybe result in fever, or some other ailment....

I just waited and waited to see if it ever got worse.... after a few years, with no change, I figured if it is abnormal maybe it's not deadly.... so I just pushed it to the back of my mind.... not knowing if I was normal or sick or what....... I couldn't risk asking anyone as I couldn't allow family to be that "close" to me... no one was safe enough for that....
