How to deal with this embarrassing situation.

I'm newly married and don't know how how to deal with a situation.

My wife loves me but she goes an extra mile by leaving hickeys everywhere on me like neck, shoulder, arm, chest to mark her territory. Since winters are yet to arrive so I roam in a simple t-shirt in my house. I try to hide them but it's impossible to hide every love bite and my mom noticed these marks on my body.

It doesn't matter how much I grow up I'll always remain a kid for my mom and she gets worried seeing all those marks on my body. She told me to tell my wife to not leave marks and to go gentle. My mom has said this atleast 2-3 times to me as she gets hurt seeing those marks (at first she thought that my wife beat me 😂).

When I told this to my wife she became upset saying mom shouldn't say like this, she says I'm your wife and it is normal between husband wife.

How should I deal with this situation so both mom and wife don't feel bad?
