masturbation while in relationships

Moe • Just trying to understand love and life right now as I enter my early 20's
How often do you masturbate while in a relation ship, I only do it once every three months cuz he make me cum but every once in awhile I'm like fuck I need it and if we're not near each other I masturbate. I don't really finger myself if we're about to have sex cuz he likes to finger me. But I was just wondering how often is it considered okay and if you find yourself in front of your partner?
