My husband is mad that I masturbate

...he’s currently trying to sleep on the couch in a one bd apartment. I am amazed. He said he feels hurt... I’m not sure what about but???? I’m so confused!

Background: we’re Catholic. Got married 6 months ago. Barely spend any time together due to his being in school and my studying for the entrance exam for medical school. We have sex mayyybe 3 times a week, in a good week.

I’m a very sexual person. If i could be having sex daily, I would. I just have physical needs that he isn’t meeting.

Am I wrong for thinking this way? Can anyone else relate? I don’t masturbate often, just sometimes to relieve stress or have some me time.
