What if I'm already fucking myself? Behind this simple insult hides a universal paradox that may put your sexuality in question. Let's do a simple thought experiment: imagine us two standing in front of each other. I, of course, am wearing a pair of jeans, that are covering my genitals and my butt. You then command me to "go fuck myself". I may be fucking myself already. I may as well not be fucking myself already. Until my dick and its position relative to my ass is observed, it is simultaneously in my ass, but also outside of it - thus, it stays in superposition. The moment you lay eyes on my penis, both states collide with each other and become either one. You may have already guessed what the problem here is. As soon as a single photon reflected by my dick enters either one of your eyes, you become gay. The only way to avoid this is to not observe my penis. But if you don't look at it, then you will never know if your insult had any effect, thus rendering it meaningless. Since you have already made the insult, you are now, too, in superposition - you're either wrong, or gay. It's unfortunate, really - you dug a hole for yourself without even knowing it. All you can do now is accept it, and learn from your mistakes.
