Tbh I find perverted MCs that have 'harem issues' more of concern than non-perverted ones. With Issei, even if some things are plain stupid, there is a good amount of development and exploration into why he has such issues. Some serious psychological shit right there. And he may go on and on about it, but all he does is strip and ogle them usually. Nothing more. And he even has his mental limiters preventing him from having particular thoughts.

Also, his epic big battles with other males(first seen with Raiser) are almost devoid of such content outside of maybe getting his 'powerup'. So when he is serious, he is badass till the end and only spouts proper moral philosophy. And I don't know about you, but his "Rias Gremory's virginity is mine!" statement is still one of the most badass things to say.

If you want some perverted MCs that do it right and generally need relatively minor motivation to make the big decisions, I have my short list. Though, I do have the list of great harem MCs regardless of sexual stuff. Issei is one of them. As a character, he does greatly(most of the time), just that the circumstances of the LN publication prevent it from going the way we please. I blame the publishers.
