Supposedly the device can also simply trade characteristics between two individuals without merging them. Would you suddenly become a girl if you traded your Y chromosome for an X from this girl ? Stoned as she is she wont notice.
You proceed to experiment once more and sure enough you suddenly feel all your proportions change as your body rearranges it's self. You pull out your phone to get a good look at your self and... You're gorgeous !
Also congratulations you figured out how to use the device to gender swap people.
