opinions please

I know it's healthy and normal to watch porn but I've spoken to my husband about it a few times and I've told him it makes me feel very insecure about my body (also he suffers from erectile dysfunction and that makes me feel so shit about myself 😥 I know it's not because of me or how I look I think but it still makes me feel so bad, I haven't felt sexy in ages) but when he watches porn he's fine and he can cum so maybe it is me, please help what should I do, I feel like it's actually damaging our relationship I just feel so sad.
