I don't think it' weird that you don't understand it, and this comes from a guy who is obsessed with them. Why is this? I don't really know because I was terrified of them and hated them until about 30 years ago. I guess for me it's because it was where I first felt like one of the guys. I have bonded with countless guys while naked in them over the last 30 years. I find that guys' guards come down when they are naked, and that they are more sociable. I have become closer with guys I knew before and then showered naked with later because we had been at our most vulnerable together. I have often questioned why I feel so passionately about open showers. I think this is the reason why. Before becoming athletic, I never got along with guys and had a terrible relationship with my older brother and father. I always longed for that close bond with other guys. A couple of times I thought I found it only to later be let down and disappointed by them (that's a whole other thread). To me, the open shower is the great equalizer. Your social position, job, wealth, etc doesn't matter. You're just one of the guys. I don't know if this makes any sense to others or not. Maybe it's just me.
