The last comment made me think: what if, in some hypothetical story, the thirty utterly meaningless relationships are the point, and the story is eventually aiming at the MC realizing exactly that point and making big changes with #31? Suddenly, the thing that was adding nothing adds everything.
While not exactly this. My first story, that I am writing until I finish, before I continue posting on SoL, is somewhat like this.
The MC and Secondary male characters are all combat Veterans, most have physical disabilities, and scars. Some have lost limbs, and they all have PTS / PTSD (Post Traumatic Stress / Post Traumatic Stress Disorder). They all have a "Hole" that they start the story unable to fill. They try to "Fix" themselves with excitement, as they are "Adrenalin Junkies" as well as Sex, alcohol, other drugs, and hedonistic activities. They are cynical, many are "minorities" and lack faith in law enforcement or justice, so they often respond with violence, usually, but not always calculated violence.
The female characters are also flawed, they (nearly all) suffer from PTS / PTSD (those who aren't quite to that level have still faced traumas). They have engaged in "survival sex" in the past, and most have engaged in prostitution. They too seek solace in Sex, alcohol, drugs, etc. Most of the female characters feel that their most powerful tool is sex! {It is said that "Females offer sex to get romance (or security). Males offer romance (or security) to get sex."}
These characters are not "heroes" neither are they "villians" they are morally grey; although some, if not most, do, at times, act in heroic manners. They see themselves as "good" people stuck in if not an "evil world" a world with a Lot of evil in it; nor are the authorities likely to provide any justice, so they must seek their own. The male characters believe they are offering, if not the best, at least a significantly better situation for the females. The females have significantly less power, and all though they haven't been in combat (well, most of them), nor have they been "Contractors" (Mercenaries) they have survived traumas most of the male charactes cannot image (and likely wouldn't survive). Objectively, at least some of the female characters, are, to a degree, experiencing "Stockholm Syndrome" (although many women feel they benefit from using sex, and subserviance to survive, even thrive). Not that all of the females are defined bybeing "victims" several of the females are in many ways stronger than most of the male characters. Several of the females are, for the most part, giving the orders, although often subtelly.
Through the course of the story most of the characters progress to a better situation; those that survive.
So, there are quite a few sex scenes, and scenes of violence, criminality, etc. that I believe are well written, but the plethora of sex is to a large degree is neccesary for many of the characters to comple their "Heroes Journey" to a HEA!
