relationships are good (admittedly, I am into shoujo manga so I have to at least tolerate that shit in general, and I often outright like it), but personally, I want the characters in my H-manga to be so lovey-dovey that they find it difficult to maintain their normal daily life because they keep fucking

like, they fuck enough and are so enamored with each other that it is a plot point that they really should probably stop (´･ω･`)
we must go past true love, past true lust, past all boundaries of decency or reason ヽ(´∇`)ノ

friends with benefits are too far from that (;´Д`)
I guess it can be okay, but that is a far cry from a love that becomes co-dependence on such a level that it is actually causing problems
