Does my husband think I’m unattractive

I’ve never posted in here, but here it goes. My husband and I have been together for a long time. He being 28 and I 27. Since having a baby 8 years ago I was diagnosed with Endometriosis and had to have a hysterectomy. I’m just now getting a sex drive back. Well, my husband has a very high sex drive and I still have a very low one. He’s all about giving me pleasure and making me orgasm, and I find pleasure doing the same. The only problem is it seems that he doesn’t ever finish while we’re ACTUALLY having sex. And half of the time he takes so long(I’m talking more than an hour) to finish that it becomes hard to stay in the mood after I’ve finished. It makes me feel very unattractive and I’ve brought this to his attention and he says he doesn’t know why. We’re always trying new things for the sole purpose that I want you to make him finish like he does me. But I really struggle with how long it takes it’s makes me feel undesirable and very unattractive.
