Please help me

I am 24 years old with 3kids.ever since I had my daughter 7 years ago I have hated sex. I feel like it doesn’t feel good to me at all. My husband always tries to get me to have sec but gets mad when I say not in the mood. I give in sometimes but feel bad afterwards.

Could this be because I’m depressed or don’t feel good about the way I look or is something wrong with me???

I’m never in the mood..EVER
