a myriad of actual medical instruments including sounds. Used heavily
the gay scene for years, these once surreptitious implements are now
globally. Seeking an edgier, more exotic form of penile stimulation,
sound has come out of the closet and into the scene play clinics and
medical devices designed to be inserted into the male urethra or the
urethra and uterus. They consist of a set of smooth stainless steel
in graduated sizes or a singular piece, which may be straight or
curved on the ends. In actual medical purposes, sounds are used for
gently enlarging the urethra or for measurements. In a BDSM medical
they can be a source of exceptional sensual stimulation. Again, with

The diameter of
sounds, catheters and some
other medical instruments is expressed in the French system. One French
unit (Fr) is .33 millimeters (.3mm for ease of discussion). Thus, an

are available as an 8 piece set in graduated sizes from 3fr/4fr to

sounds have double sizing on each. For example, the 3fr/4fr sound has a
3fr width on the one end to about half way down the sound (11cm or

detergent solution (detergents remove surface lubricants or surgical
jelly and help
break down viral coats). Allow to dry on a clean towel. Use an alcohol swab
over the instrument before insertion during next session.
Updated note: we
highly recommend only using insertables,
speculum, anal toys, sounds,
etc. for one person usage, only! Sharing or "sterilizing" for use with
multiple persons is very risky without proper anti-HIV, anti-STD
sterilizing procedures and equipment.
popular medical device
for both males and females in the medical BDSM scene is the Speculum.The
actual medical application is examination of the rectum or the vagina.
Usually, it is made of steel in a duckbill shape with two "jaws" which
"open" with a screw-type mechanism, thus, stretching the opening to
a clear view down the center into the vagina or rectum. There are also
plastic disposable variations of specula. Objects such as swabs can be
inserted through the opening into the orifice. It also allows for
cool or warm water into the opening. However here's another caution,
DO NOT use water that is too hot and DO NOT use ice since they can
damage the delicate tissue lining inside the anus or the vagina.
