I'm not saying that Issei doesn't like their bodies, he still likes it but he can not be excited about it like a child when he first did. Imagine this, you really like a lolipop, and you eat it everyday, after some time you would get dull with the lolipop, of course it's not that you dislike/hate the lolipop, you just lose the initial interest in it.
