This might come under the heading of news you didn't want to hear:

Aviation physicians recommend that a pilot refrain from
operating an aircraft for six hours after taking Viagra. This is
especially true if he intends to fly at night. Of course, this also
means that a pilot should definitely not use Viagra to enhance his
performance while joining the "mile high club," in which membership
is achieved by sexual activity a mile above the earth. The
combination of a sexual exertion at a 5,000 foot altitude at night
could prove a deadly combination for a pilot and his loved one.

Courtesy of the Aero-News Propwash newsletter, which notes that the
risks are especially high if the pilot is over 65.
