It's so weird having an entire appendage that just doesn't have any muscles in it.

If I tell my arm to move, it'll move. If I tell my leg to move, it'll do so also, and neither with any particular resistance to it. But if I need to move my penis, I have to physically adjust it with my hands, otherwise it kinda just hangs there limply. Why do we just accept this as normal? Like it doesn't cause many problems bc that area is fairly well-designed, but it sure is weird as hell.
