Adams Rib and Homosexuality

I was reading a list dealing with sexuality on a comedy website yesterday, and in the list it made reference to Eve being made from Adam's rib. This got me thinking....

Since technically Eve was made from Adam, shouldn't women (biblically speaking), be considered at least part man? Doesn't this destroy the whole "man should not lay with another man" argument? It's all right there in the name, woMAN!

If sex is okay between a man and a woMAN, then why not two MANs?
