Do you ever get worried that your boyfriend has a fetish and you are the very specific type of person that he is attracted to and that if he suddenly stopped being attracted to you he'd stop caring about you?

He said he's basically never been attracted to a girl before and then I came along and he's obsessed with me. He also obsessed with my very specific body part. I know he loves me but I worry he doesn't see me as a person and that as soon as he stops finding me physically attractive he'll start treating me very differently.
