This really does make sense to me as I can attest to how it is to not being able to attract women to the point they want to jump your bones and to know that you basically made them come up with a REASON to do it that is in their interest to do so.
This is something I barely think about, but I used to due to one of those clean and morally upright backgrounds you mention. Are you saying that it is also "inability to have sex with women who have genuine desire to have sex with you?" This is another nod to the difficulty of creating a concise definition for "Incel." Well, here I am saying this and people don't even bother to know what words with well constructed and concise definitions mean before they call someone something anyway. "Misogynist" or "Chauvanist" anyone?
More like the inability to find any woman with a genuine desire to have sex with you in the first place.
What I mentioned was if someone who can't find a willing partner, decides to pay for it (for whatever reason they are paying for it), and decides to go one of the routes like dumpster diving, paying for play, etc... and has post nut clarity afterwards, then it could be a choice filled with regrets or haunts.
For example, I can say I'm unable to find a willing partner to have sex with. Therefore, being 50 years old, let me find a barely legal, 19 year old girl and pay her for a good-time. After post-nut clarity, then you'll feel like a predator, pedo, taking part of trafficing, maybe wonder, how such a wonderful girl got caught up into something like that, is she really doing this voluntarily or is she being controlled by a pimp, did I catch stds/demons from her, etc..... That's an extreme example. You also have milder examples but the principle is the same. Promiscious women/escorts, have been with a large number of guys, have a lifestyle that's polar opposite (drugs, going to parties, getting stoned/drunk, etc...) where if you just come out of the blue, clean and upright, pay for just a brief encounter with them, it's going to be a shock to the system because their reality is too different from your reality as a straight/moral person.
