You don't have to worry about it. When they meant that Issei is becoming less perverted being he is growing up. DxD is not all about demons and ecchi, is about those guys being "human" aka the girls dealing with love and family trouble while Issei was living in a fantasy about having a harem solve everything. But Issei is growing up, realizing there is more thing to worry about like that new demon factor (cannot spell the name) and Issei is still a pervert, but more in control of it, like vol 18 life 0 where he stop himself from gropping Rias during a important moment.
