Penis envy! (Ducks and runs for cover...)
Only a man would invent the theory of penis envy.
The ONLY time I wished I had one of those attachments was when I was stuck in an elevator and the guy I was with could have relieved himself rather easily and I could not.
I think we women, being smaller, weaker, and nurturing, were made to be protected and taken care of by men. Unfortunately when a man doesn’t fulfill the obligation (frequently because women give away their trump card) then we have to fend for ourselves - which goes against our nature for the most part.
