Absolutely love the comic, but you kinda missed the page 17. If its because of a little ecchi moment there (yeah, I found the page on other resource, hilarious) , I don't think you should be concerned at all. They allow ecchi and ero here, so, as long as its not mating/porn, or graphic display of primary sexual characteristic its perfectly allowed.
