Should I feel bad about masturbating without my boyfriends approval?

So I am recently slipped up and my boyfriend found my vibrator. He got a little upset due to the fact he thinks he doesn’t satisfy me, which he does! The problem is I’m a nymphomaniac, I just love sex and orgasms. Of course I can’t cheat on him cuz I love him so much but the days when I’m at work and he’s at school, I just need to release.

He made me feel guilty about it cuz I want him to know he’s perfect in the bedroom but I just want sex more often than he provides
