In terms of the “royal you”: Know that partners honestly, really don’t care what it looks like as long as you know how to use it. And if they do, meh. Not worth your time.
Bahaha Sir just texted me like “the way to get over penis anxiety is to stick in it her butt. Then you’ll realize the value of an average-sized penis.”
So, there you go.
