Potty Thoughts - the end?

I was thinking back to my days in college and the dorms (residence halls) we lived in. I always wondered why the women's shower stalls had curtains and the men's didn't. Now, as we all know most men are homophobic and worried about seeing another guy's privates. And yet with no curtain, a preview is practically forced upon you. Women on the other hand often change in front of each other and walk around half naked in their shower and locker rooms. So tell me, where is the sense in this? Wish I was a woman. +)
