There's a student in medical school who wants to specialize in sexual disorders, so he makes arrangements to visit the sexual disorder clinic. The chief doctor is showing him around, discussing cases and the facility, when the student sees a patient masturbating right there in the hallway.
"What condition does he have?" the student asks.
"He suffers from Seminal Buildup Disorder," the doctor replies. "If he doesn't obtain sexual release forty to fifty times a day, he'll pass into a coma."
The student takes some notes on that, and they continue down the hall. As they turn the corner, he sees another patient with his pants around his ankles, receiving oral sex from a beautiful nurse.
"What about him?" the student asks. "What's his story?"
"Oh, it's the same condition," the doctor replies. "He just has a better health plan."
