How about some h/c for Itachi, Deidara, Madara and Kakashi and how they would react to their bored s/o just dropping the sappiest/shittiest pick-up lines on them? Also it might be a bit late, but I think it's fine to be gender-specific with certain things (like nsfw or pregnancy). Otherwise it really is difficult to write. I think specifying gender in such cases shouldn't be a problem. First and most important it's your blog and you should have fun with it and your writing!!
