you are only getting it half right by simply calling hentai “pervert”…there is more to the word than just "pervert"
It’s really hard to precisely explain this in english terms…but the best term I can think of for “hentai” (which is an adjective btw) is “perverted FREAKY”…you don’t call someone who watches porn “hentai” (your girlfriend may if she got really angry), but you would call someone who walks around at night wearing nothing but a trenchcoat and showing his body to all passersby "hentai"
Because of the extremely negative implication fo the term “hentai” it will be really bad to refer to these games “hentai”. If you were in japan, say in akihabara or in comic market, and you yell “Kanon is hentai game”…I can assure you that you will get a good beating by an angry mob and nobody will pity for you…
This is something you cannot learn by simply taking japanese classes…and something they obviously don’t teach either
Anyhow, my suggestion is: don’t use the term hentai unless you have a good reason for it…but then people here have already associated the term hentai already with any adult anime material, tasteful or not, which is of course a really sad thing.
