A man and a woman

A man and a woman were sitting beside each other in the first class
section of an airplane.

The woman sneezed, took out a tissue, gently wiped her nose, then
visibly shuddered for ten to fifteen seconds.

The man went back to his reading.

A few minutes later, the woman sneezed again, took a tissue, wiped
her nose, then shuddered violently once more.

Assuming that the woman might have a cold, the man was still curious
about the shuddering.

A few more minutes passed when the woman sneezed yet again. As before
she took a tissue, wiped her nose, her body shaking ever more than before.

Unable to restrain his curiosity, the man turned to the woman and
said, "I couldn't help but notice that you've sneezed three times, wiped
your nose and then shuddered violently. Are you ok?"

"I am sorry if I disturbed you, I have a very rare medical condition;
whenever I sneeze I have an orgasm."

The man, more than a bit embarrassed, was still curious. " I have
never heard of that condition before" he said. " Are you taking anything
for it?"

"Yes," the woman nodded. "Pepper."
