When receiving sexual stimulation for pleasure from another person (male or female) you interrupt them to explain a past partner performed said act with a lot more skill. Then you allow them to continue said act.
I tell you I Kanye West'd her last night? I said "Yo Taylor, I'm gonna let you finish, but Ashley gave the best head I ever had"
