You can avoid the Carmen Blue Balls scene by just having a bed partner, since I almost always keep having either Ryn or Azzy with me I have only ever seen that scene a single time. Actually didn't know until now that was what triggered it.
Agreed with Masturbation point, but not sure what the training inconsistency refers to. Some training sessions not passing a day? I think they all should so that would be bugs to report on. Otherwise main thing I know of is Zo's training scenes saying that's enough for one day, when really (in current build) you only need a day to pass once you have unlocked a power so that the next button can appear. I tend to just skip over to the Puppers and let time pass for that.
Yeah, mean outside of that. Carmen claims that it's a "dream", yet neither the Ring of Pure Thought nor turning Dream Events off bypasses that scene.
Yes, alleviating the "Blue Balled" status effect bypasses getting the scene, but at higher Libido the Blue Balled status affect can occur whilst sleeping (so, prior to sleeping, no Blue Balled status effect, then during the sleep the status effect occurs), and causing the scene to occur without any way to avoid it (at least seem to recall that interaction happening before).
Same criticism goes for Viviane's scene when the champion gets the Witch Outfit (or her Halloween scene, as they seem to be the same scene, though the Halloween version of the scene is avoidable with Holiday Events off) - no way to avoid her coming on to the champion whilst they sleep - so effectively her recruitment cannot be done without letting her violate the champion - and it's canon that she does that (and therefore, not a dream, as the Wiki seems to want to imply), because she brings it up when the champion meets her in the forest.
Same criticism with Kasyrra's scene if you try and fight her in the "dream" she overpowers the champion and... so yeah. No way to avoid these things other than "don't try xyz" or "don't interact with abc" or "actually avoid going to region def".
The training inconsistency has already been reported on the CoC2 Bug Reports sub-forum, and has been brought up here before a couple of years ago. It's still in the game, so at this point the developers must be fine with it being in the game, hence just mentioning it as a gripe and not further reporting it as a bug - because doing so seems like it would be a waste of time, well, arguably more of a waste of time.
