Bf claims he has ED

My bf claims he had ED. Our sex life is rough. He tells me I’m sexy and is always wanting me, but He can never keep it up. But I’m also constantly catching him watching porn and jerking off with it just fine. I’ve never been uncomfortable with my spouse watching porn or self pleasuring. But my mind is everywhere with the fact that I can’t keep him hard or get him off, but touching himself to porn does. Anyone else experience this? Or is there just something wrong with me?? I’m beginning to feel less attractive and not Womanly.. I’m questioning a lot about myself 😳😩
