The feeling after a man masturbates where he feels tired and/or wiped out. His dick will most likely be floppy and/or also tired. After phone sex the post jerk will inhibit the mans ability to keep speaking on the phone, especially at night. Never bother a man in post jerk, he may freak out
betty: damn, my boy friend and i had hot phone sex last night but it was so awkward after he barely answered me

Sarah: he was probably having post jerk
