This article is from the Piercing FAQ, by Anne Greenblatt with numerous contributions by others.
Genital piercings are intended to enhance sensation for the wearer
and, in the case of male piercings, his partner during
intercourse. However, wearing genital jewelry does require caution
during certain activities, particularly if the piercing has not yet
completely healed. In some cases, the desired activity can be impeded
by the jewelry.
New piercings do not prohibit sexual activity. However, exposure to
the partner's bodily fluids must be prevented to reduce the risk of
infection, even in a monogamous relationship. Numerous microorganisms,
including bacterias and yeasts, are present in genital and oral
cavities. Saliva should not be used as a lubricant for masturbation or
intercourse while the piercing is healing. Both partners should wash
their hands before touching the jewelry or the piercing. Latex
barriers (condoms, dental dams) should be used during all
genital-genital or oral-genital contact. After piercings have
completely healed, they are no longer susceptible to infection and are
no more susceptible to transmitting and contracting disease-causing
organisms than the surrounding skin (mucous membranes are naturally
more susceptible). However, piercings can be injured by strenuous
activity or recent stretching; minute and non-visible tears within the
piercing which yields the piercing susceptible to infection and and
disease transmission.
In the case of Prince Albert, Ampallang and Apadravya piercings,
erection or orgasm may cause the piercing to bleed during the first
week. Strenuous sexual activity during the healing period may prolong
healing and cause uncomfortable scarring.
Penis piercings with average-sized jewelry rarely interfere with the
safe use of condoms. Condoms with larger receptical ends will fit
comfortably over penis jewelry. Lubricating the inside of the condom
as well as the jewelry itself will reduce friction. Diaphrams and
cervical caps can be dislodged by curved barbells or circular barbells
worn in the Prince Albert piercing.
Penis jewelry rarely impedes comfortable male-female intercourse.
Comfort and stimulation are greatly influenced by the position of
intercourse and the relative dimensions of the penis and
vagina. Discomfort to either partner can often be alleviated by
changing the dimensions or style of the jewelry. Some women find
piercings with barbells, such as frenum, Apadravya and Ampallang
piercings, uncomfortable. Shortening the barbell or wearing smaller
barbell balls may reduce discomfort. A frenum barbell may be
substituted by a ring. A large diameter ring which snugly encircles
the penis behind the corona (ridge of the glans) can be worn if the
placement of the piercing allows.
Discomfort caused by friction against the jewelry or friction within
the piercing can be alleviated by applying a water based lubricant to
the jewelry.
Exerting pressure or pulling on jewelry that is too thin will be
uncomfortable and may injure or tear the piercing. The thicker the
jewelry, the more surface area over which pressure is distributed. The
depth of the piercing should also be considered; a shallow piercing is
more likely to tear or be injured.
Most men have found that penis piercings 12ga or thinner tend to be
uncomfortable or pinch during sexual activity. Once the piercing has
been stretched to a thicker gauge the pinching sensation disappears.
There is no evidence that piercings of the penis cause urinary tract
infections in either partner.
On rare ocassions penis jewelry has been known to chip teeth or become
lodged in the partner's throat during oral sex.
