It's not entirely that, you know how I mention that your art should speak for itself rather than for you doing so yourself? Unleash your thoughts into your art. You ever seen a model and they just make whatever they were modeling POP, that's what I mean that a piece or even a objective should speak for itself.
Here's another examp, you ever seen a show or even had interest in a particular person and their interest seek through what they do but it's subtle and other people can get the gist of it? Lets say you made a character, right, a new oc that you made, POP, and you want, let's say, seek their sexual interest. What you would do is show subtle signs in how they express it than fully putting it out there. This would give people in trying to figure out what your piece mean than for you to fully leak your own self-insert into them.
