I'd also like more attention paid to Hinata, because well, it's Hinata, and everyone is attracted to her.
She's perhaps the character people desire the most, besides Tsunade and Sakura. But demanding that Hinata isn't being given attention isn't a valid complaint; it's a personal desire.
Furthermore, Hinata's path is more complicated; she won't give in to Haruto easily, nor would it make sense for it to be easy. There's a long way to go before she dares to even give him a handjob.
This will require deception, submission, and a desire for Naruto's lack of sexual attention. I can imagine some solutions for Haruto to make advances toward Hinata, like Shizune explaining that Haruto needs to orgasm constantly or he'll have health problems, but his arms end up breaking, and only Hinata can help him, since Haruto doesn't have a girlfriend.
But the other girls' paths will be faster than Hinata's.
