My (23f) boyfriend (25m) asked me to stop singing

I’m a terrible singer. I sound like a guttural cat dying. But I like to sing when it’s just me and my long-distance boyfriend in a car, bathroom, bed, etc. (I’m spending the night at his place this week, I live two cities over). I asked him (nicely but also firmly, lol) to stop asking me to stop singing or to make jokes about my singing. I told him it’s pretty hurtful. I don’t want to think twice before singing some random random song in the car, that’s not a comfortable relationship to me. When I told him this, he said it’s offensive how bad I am. Is that a reasonable response? Is there a way to let him know singing isn’t THAT important to me, but it’s not important enough to laugh at me either? Or am I being too sensitive, and should let him joke because it’s just so bad?<br><br>Edit: I’m aware I’m a bad singer, it’s not an insult when he says stuff like that! But yes I was hurt when he told me to stop being silly and that I hurt his ears, or when he makes faces with my friends when I start singing. That stuff bothers me.<br><br>Edit two: I get that he’s just joking! But that doesn’t mean I’m being too sensitive when I’m hurt, that means he’s doing something that hurts me.
