Newbie here. How would you do so properly?

You son of a bitch - I'm in!

I would watch the CRAP out of this!

I choked on my coffee, thank you.

I would prefer them separate, because - as I am not deeply familiar with anime/anime-like styles and any age indicator they might have (breast size does not count) - I cannot tell when the subject is supposed to be underage (and even if they are, sometimes it's up for interpretation). I have a much better chance of guessing correctly with the realistic style. I desperately want to believe that every artist is always drawing 18+ (assuming USA), but that is left up to the thin blue line, not the artist's intention, and that is NOT a line I want to end up on the wrong side of.

If I don't have my own, will store-bought do?
