This article is from the Piercing FAQ, by Anne Greenblatt with numerous contributions by others.
Genital piercings often bleed between 12 to 24 hours depending on the
depth and complexity of the piercing. Prince Albert, Ampallang, and
Apadravya piercings may bleed intermitantly for several days,
particularly during erections. Triangle piercings may bleed
intermitantly for several days.
Genital piercings should be cleaned following the instructions for
body piercings. Some antiseptics and soaps can irritate the urethra in
both men and women. After cleaning the piercing, urinate to flush out
any residues in the urethral opening.
Women should be careful to prevent the antiseptic or soap from
entering the vagina and to rinse thoroughly with running
water. Depletion of the bacteria naturally present in the vagina can
cause yeast infections (Candida albicans). Women should use the most
lint-free toilet tissue available. Unscented pantyliners may be worn
if the piercing bleeds. During the healing period do not wear
pantyhose which restrict air circulation and are often uncomfortable.
Do not allow your piercing to come in contact with another personšs
bodily fluids while the piercing is healing. This includes saliva (of
others and your own) as well as semen. Your own urine is
non-pathogenic as long as you do not have a bladder or urinary tract
infection. There is no need to clean the piercing after urinating,
although it may burn during the first 24 to 48 hours. While a new or
healing genital piercing does not prevent sexual activity, appropriate
barriers should be used (condom, dental dam). You should not feel pain
during sexual activity after the piercing has healed.
