No, it doesn't not and you're right. Trying to be helpful and making things clear is sometimes a vain exercise. Some will still go beyond the "do not enter warning" and wonder why they got hurt.
At least, at The End of Time, when I will face The God of Bewbs, I could say : I tried
True as a counter argument from someone who is not a giant titties fan even if I do like a big breasted girl especially if she has a nice figure as well and do not discriminate nice girls. Really the girls with the most content are pretty big even for big tits, a bit more content for that poor girl with the push up bra and a complex about her size compared to other girls and Delizia or Brenda would not hurt and might help for the guys that are less into real big tits into finding out that most of those girls are pretty nice to interact with anyway and not a chore, despite their handicap.

(just teasing with last word)
Regarding the sex scenes, yeah they are gettable though for a first timer like me might take a bit longer as for you veterans that understand the game and mechanics better. Especially if your natural taste might lead to choices with mainly having the girls with less content on island. Lol actually Joy was my first sex scene, kinda enjoyed that one where she misplaced her escort.
Guide helps with that, but fact that most of those scenes hide behind quests that are not in themselves logical to get most of the time(as a quick example doctor scene I never unlocked yet so not sure how far that goes if do not have an ejaculation for a few days. Well you can get the idea such a scene may exist when get that email after a day not masturbating or coming, but it makes no logical sense with how game is setup that would be a good thing to do, it is counter intuitive and purely a game mechanic of searching for content you already know is there, instead of getting content by just playing game to build relationships

) , is as someone said before actually part of the more gaming mechanics to make it feel as a game, but does not per se help that. That approach has both advantages and disadvantages.
First big scene with a girl that comes more from the flow of developing that relation might work even better, then again it seems that is what Amy prototype is exactly about and the new girls added which have a questlog from quickly after meeting them. So game does improves on that part, with the slight comments I had on the balance of that Amy line and I personally and not as a demand would like the earlier quests to give a higher max affection and love and later more focus, so it would feel more like interacting with her is worth it for some progress while the quest runs instead of having to wait until the next part of quest triggers or you made sure the conditions for that are right and interacting with her is mainly useless in meantime.
