Large and almost constant erection

A guy walked into the doctor's surgery for an appointment.
"Would you like to tell me your problem?" the pretty receptionist asked.
"I'll need the information for the doctor."
"It's rather embarrassing," the guy stammered. "You see, I have a very large and almost constant erection."
"Well, the doctor is very busy today," the receptionist cooed, "but maybe I can squeeze you in."
