When I was in High school, I had hickeys often enough. They never showed. May I add that I was a virgin all through school...but still had boyfriends and secrets from Mom and Dad. High schoolers experiment...hopefully only with hickeys.
At this age, I do not like having hickeys. I don't want to go to work and have people staring at my neck. I have a wedding ring to show people "he loves me."
On a side note, I remember in high school, people were always coming up with crazy ways to get rid of hickeys. Did any of them ever work?
