Invulnerability.

That's right, I'm indestructible! No matter how hard you hit me I feel no pain and I don't break. I'm stronger than most so I can pretty much take on any baddie who tries to mess with my city. I always believed that being invincible pretty much meant that I was undefeatable. In order to measure up to the high standards I set for myself, I have bequeathed myself: the Golden Muscle whenever I am in costume. Pretty neat huh? However, just because my spectacular body can't be destroyed, doesn't mean my clothes can't. I have encountered too many scuffles where I endure a great deal of humiliation because of the peace-of-mind I naturally have from being invulnerable.

Time after time, I would take a hit that would dissolve, tear, or just completely remove an article of clothing off my body. Since I don't feel pain and I am often too focused on saving the day or getting attention from my adoring public I don't often notice that I am being stripped until it is too late. And even when I do notice, well...it doesn't exactly make things any less embarrassing when I'm still stark naked in front of a bunch of gorgeous girls.

This is a story on how my invulnerability got me humiliated in a public setting with various wandering eyes that honed in on my dick.
