True a non perverted Issei won't be Issei. How to become Harem King if not perverted? Through love perhaps.

Well jokes aside, the probable reason why Ishibumi reduced Issei's pervertion level at this point is because just being perverted at this point won't help Issei further his relationship with the girls who are already in love with him. Issei needs to show that he loves them not just for his perverted desire but love them as females and for what they are.

Then again, hopefully we'll get to see new girls soon. We've been getting nothing but Dragons and men lately ( ._.)
