There is an important lesson to learn from men, biologically born men. Take a look at a man dancing, stop criticizing his lack of rhythm, now look again closer. Notice how his package is not making its way down his pants. No, it stays right between his hips. The chimney may sway but the roof stays solid. Next time you are rocking your bulge take this in consideration. There is nothing more distracting than watching a butch / drag king / FTM / gender queer / etc. moving their hips back and forth on the dance floor while their cock is sliding down their pant leg.
Strap it tight or leave it at home. And, I would really rather you not do the latter.
