A Doctor recently had a patient "drop" in on him for an unscheduled appointment.

"What can I do for you today?" the Doctor asked.

The aged¹ Gentleman replied, "Doctor, you must help me. Every time I make love to my wife, my eyes get all bleary, my legs go weak, I can hardly catch my breath.... Doctor, I'm scarred²!"

The Doctor, looking at his 86 year old patient, said, "Mr. Smith, these sensations³ tend to happen over time, especially to a man of your advanced years, but tell me, when did you first notice these symptoms?"

The old gent's response was, "Well... three times last night, and twice again this morning!"
