"Issei was one of the lucky perverts in anime history because his house was being renovated for free and also having polygamous relationship with the 3 factions"

I direct you to this. Main difference is that the MC isn't really a pervert, mostly an accidental one. House getting renovated for free for additions to the harem is similar. Also the guy stated that he has decided to choose at least one of them to marry. Just that the series is way too funny to actually go into that anytime soon. The factions part is debatable however since despite them being various mythological creatures, they are basically one faction. The ecchi level is on par or greater than DxD but way more hilarious since it isn't a dead-serious or deep storyline. Contains more borderline Yuri though....

I would say that the Monster Musume series is what DxD would look like without the serious aspect or...... the..... "high school" in the..... Whatever >_>

"tend to increase his manliness/devilish/pervertish instinct"

What? Where? Show me! I'm going blind!!! DX

Just Kidding =P Nah, at home the guy is pretty toned down and judging by possible spoiler info, his perverted tendencies decrease. Right now he comes off as an extreme but still in-control siscon towards the girls living with him. =P
