The story is about a cross-dresser who goes out for an evening drive all dressed up. Stops in a remote place and is abducted by aliens. There is a discussion with the aliens that concludes with them "helping" him by correcting an anomaly in him. They release him and he finds out that he is now a she. The final line in the story is him/her wondering how he/she will explain it to his/her wife...

I think the author may be Valentina Michelle Smith, but I can't be sure.
