Can reading erotica ruin a relationship?

Elizabeth
Does anyone think that reading erotica can ruin a relationship? 
I personally like reading erotica but it seems like my fiancé gets jeolous. Sometimes he will ask me questions like " Are all the guys handsome" " Are they always rich" "Is  that what you want". Questions that seem like he doesn't like me reading that stuff.
I love my fiancé so much and I find him so attractive.i don't want him to think that the guys in the books are better or more attractive then him, becasue there not.
Those books are just a hobbie for me. And now I feel bad that I read them. 
So i had a lot of books in my kindle that I bought and some that he got me that I've been collecting over the past year. I felt really bad one day and I deleted all of them from my kindle. I did it becasue I didn't want him to feel bad anymore or to think that what I read is what I want him to be like or to act like. 
Believe me it was hard to delete those books. 
So I finally told him I deleted all the books and he was upset about it and he said that it was a hobbie to me and that he didn't mind. But really I think he does mind. I miss my books so much it's been like two weeks or so without them. I want to go back and read more but I dont want him to feel bad about himself if I do read them again. So I'm asking you lady's if you gals could give me some advice or something please. Sorry so long
