Sigh...

If you don't understand ecclesiology, I am not going to teach it to you.  Suffice it to say--you can't just arbitrarily decide that God has not spoken just because the pope has made a decision about dogma that you don't like. 

There is a biological reason why women cannot be ordained: they do not have a Y Chromosome. In order to be ordained to the priesthood, one must be male.  You are right about there being no psychological reason why women cannot be ordained. I am not aware that the Church tries to argue there is a psychological reason though.  There are many theological reasons why women cannot be ordained, but the chief reason is that women cannot be ordained because God has not given the Church the authority to ordain women.
