Someone told me that because vitamin K was found in the rectum, having unprotected anal sex could cause erectile dysfunction since the the penis would be exposed to this vitamin K.
I have personally never heard of this before. Anyone know anything about this?
Waitaminute? Vitamin K meaning the vitamin? Or mean ketamine, a popular club drug in the gay community? The latter has an inhibitory effect, but I don’t know if it affects ED and it traveling to the rectum and affecting another is iffy.
Or someone didn’t want to try anal, and made this up to shut their partner up.
