It's just like this, you eat steak for the first time in your life after 17 years and you've been eating since. Surely even if you like it, you'll lose interest or feel dull about it after a while. This is kinda like the situation Issei is in right now. He's been exposed to the girls' body for like half a year already, even if Issei is perverted, he should have gotten used to it to the point he might not feel much about this anymore pervesely
