>So where should I learn how to draw big boobs, anon? Legitimately asking. Not trolling. Not howie.
Use a mix of heavily curated real-life and hentai references. (I say "heavily curated" because I've found that most real-life references are about as useless as hentai: the former are ugly more often than not, and the latter are too absurd.) Lurk /gif/ and /s/ for real-life references. Lurk Gelbooru for hentai references. Every so often, you'll come across nice things.
>The Japanese books on e-hentai about drawing boobs are bad imo. They don’t even look right.
I agree with this. The intersection between the minority of hentai artists who know how to draw proper boobs and hentai artists who are able and willing to make tutorials is incredibly small. I don't reference tutorials for this reason.
>I don’t mind copying excellent hentai artists. But which one?
This is really a question of preference, but I think nypaon and poriuretan(?) draw nice big breasts. Both of these artists I found by lurking Gelbooru.
