As a result, during his frequent sexual conquests just outside the shared dining facility, he would forget the names of the people providing fellatiatic services, or even why they were there. He was suffering from dimentia dick.

Usage 2: I invited a guy from a dating app to come to my house. Now he’s riding on my cock but I can’t recall his name. I have dimentia dick.
