Occurs when having
sex for an extended period of time, vigorously, or with a woman with pubic stubble. Friction from the rubbing of the
skin between the penis and labia majora will cause a rash to be produced. Symptoms include redness, swelling,
pain, and sensitivity usually on
one or both lateral sides of the penis in a line extending from the base to the tip. More severe rashes will usually develop a slight darkened scabbing within 12 - 24 hours from intercourse and heal within 3 - 7 days without treatment. To reduce symptoms it is recommended for the men to refrain from
sex and masturbation, wear loose-fitting cotton underwear, take ibuprofin as needed for
pain, and use a condom with future encounters. For the woman to
help prevent future occurrences with men, shave cleanly before and use lubricant during intercourse.
