I think this question requires quite a bit of explanation. Until fairly recently, it used to be common to refer to the whole human race as "man", (as an example, in the introduction of the early Star Trek series episodes they used to say "...to boldly go where no man has gone before"). However, today it is considered politically incorrect to refer to all of humanity as "man", due to feminist movements. So, the answer to your question is that you should say "all sorts of people", because nowadays "all sorts of men" would only be used to literally mean men, not women. You may still see this old form in literature, and to give you a concrete example of how this has changed, the more recent Star Trek series changed their introduction to "...to boldly go where no-one has gone before". I hope this has helped clarify the issue for you!

Yes. Men are basically people with dicks.
