"Boring" depends on whom you ask. If you ask a few members of this forum, I'm sure they'll tell you that they find it "boring,"; not boring enough to stop reading, but boring enough to complain about it. If you ask me, I can read up until Immoral Desires #152 of just Lana and Daniel having sex, and I'd be be just as engaged as I am now, because I, personally, don't derive excitement from multiple pairings; I don't dislike it, but I don't measure my enjoyment based on how many females the MMC has sex with or how many males the MFC has sex with. And by the numbers, Immoral Desires has soared through 11 Full Chapters of virtually just Lana and Daniel having sex. Not just that, it's more popular than his comic that has a male character who has sex with multiple females, and his comic where his main female character has sex with multiple males. So I don't know where this "worry" if one could call it that, comes from about Immoral Desires burning out, at least outside of the expected tapering off that many if not most long-running comics have.
