Those are definitely some interesting things to tell a girl you meet for the first time. I"ll add them in to make sure they act disgusted rather than confused.
Like Onionknight says, you can use a button mode if you're really struggling and yeah, very basic words will work. I've added a few common misspelling of words, but for some more specific responses, you will need the correct spelling to trigger, but let me know which words you really struggle with, I don't mind adding them in.
I don't know about other devs, but my reasoning is more that it wouldn't make much sense, since not all of these girls would be okay with sharing you.
Thank you and it's cool. Sorry, I can't fulfill your harem wish, hope you can find some great games that do.
