First off, this is a harem series. Second, Rias, Asia, Akeno and Koneko are already confirmed as part of Ise's harem, that will never change. Third, Akeno loves Ise perhaps even more than Rias, both Akeno and Rias nearly lost their will to live when Ise died. Fourth, Vali watch porn with Ise in Volume 18 not 19, and that is because Azazel tricked Vali into believing that watching porn will help him become stronger. Throughout the process, Vali was asking Ise this and that on how can he convert the ability to watch porn into power, so no, Vali isn't interested in women nor is he perverted. He's only interested in gaining strength only.
