Groundhogging
During sexual intercourse, you witness something so incredibly disgusting that you lose your erection and your penis recedes in towards your body. (Much like how when a groundhog notices his shadow and runs back into his hole.
I was about to start fucking this girl I met at a bar, when I pulled down her pants and noticed she had open sores covering her pussy. It was so disgusting my penis went groundhogging.
