When something is so vile and such a massive turnoff that your penis literally panics and retreats back into your body. This is a defense mechanism and natural instinct so your penis can not be sexually violated by what has been deemed so repulsive.
When I had found out my mom's ex boyfriend texted me about how horny he was, thinking it was my mom's phone number, it gave me a reverse erection.
