He decided it'd be fun to be another person's genitals, while retaining his appearance. "Alright, now how will this one work..." Scanning through the list, he found the Penis option, and clicked on it. Different settings opened up, and he looked through, setting what he wants.

Without double checking, Jeff clicks the Confirm button, the options disappearing as the progress bar pops up. He sits there and watches it for a few minutes, to make sure it all works. As the bar reaches 50%, a pop-up box appears, with instructions;
"Instructions on attachment:
Simply insert host's penis into target's body. In the case of the host being female, Simply inserting either the upper or lower half of the target into any part of the host's body will also connect.
With the selected settings, if inserting lower half, it is recommended to have the target's crotch outside of the host's body."
While Jeff was reading the instructions, The bar hit 100%, and he got ready. That's when he realized. "Wait... I haven't selected who I'll attach to!"
