For a modern woman, once you have protected sex with a man, then you want to BE a man, then you want sex with a woman, then you want to be both a man and a woman.  Post Hoc Ergo Propter Hoc. The peer-reviewed research is clear on all this. Alas there are no major research universities approved by the Newman Society so you'll have to take my word for it. Or maybe Life of the Lay can connect the dots for you.
