Getting a hickey!

My boyfriend of 6 month gave me a hickey by mistake and my mom saw it. When she saw it she got extremely mad. But in my opinion I don't see the flaw in this as why does it matter, I'm human and humans like to get physical. I'm 18
What do y'all think about this?
Adding on: she got so mad that she wants to call his parents as well to inform them on this
