I think it's just a metal plate, exo's are modelled after humans so there are male and female variants, except they cant reproduce, or kiss, just intereact with humans on an emotional level, but i dont think they can get horny or fall in love
Dude, USB shaped like a D*ick. Holds anywhere from 5000-10000 GB depending on size, has a vibrate function, and you can take the top on and off for both the sexy hardware and the ladies.
Exo don't reproduce sexually. They were created by humans during the Golden Age. Their sentience and ability to become emotionally attached would be a better topic of debate.
