I'm not saying he is going to add all these girls in and give them development. Just show in the future that they are married to Issei and in his harem. But some of them would be an asspull. The great thing about this series is that there are a lot of unique and interesting characters. But when focusing on developing one of the girls, the other girls take a backseat. So there is a limit to how much Ishibumi can put in. I just can't see Issei having less than 20 wives. He is already famous and strong, so women will be coming at him. And his dragon aura just adds to that. Like Venelana said, women are attracted to men that are charming and strong. And also women are also drawn to status, money, and power in men. So Issei will have women throwing themselves at him: some for his genes, some just for a good time, and for other things as well. We see this a lot in real life as well. That's what I think Venelana was telling Rias when she told her to control the harem. I think she wasn't referring to the current girls, but the later ones to come considering Issei's rising fame in the Underworld. I bet my money that Diehauser Belial has a harem and the rest of the top ten. Imagine Issei's fame when he starts competing in the professional Rating Games.
