Masterbation and Inadequacy?

Okie Beautiful Ladies!

My husband has a issue with me masterbating when he is home.

DH(dear husband) has quite the Sex drive, as to where mine has been lacking since we had our first son.

He thinks that I need to save masterbation for when he isn't home, because when he is, he can take care of me. However, sometimes I just dont want sex.

DH masturbates a lot when I am home, due to his high sex drive, because he knows I'm not up for sex every day. But because he is always up for it.

Is it wrong of me to want to scratch my itch myself instead of letting him do it.

Is it wrong of me to not want to have sex with him as often as he wishes, and want to masterbate when I get an itch?
