THE PENIS
1. THE PENIS
=MORE PROTRUSIVE/NOTICEABLE THAN
EXTERNAL FEMALE GENITALIA (makes more
males feel insecure/familiar with their
penises)
=
A. GLANS = HEAD OF PENIS, ON TOP OF
PENIS SHAFT
=SIMILAR TO CLITORIS
B. CORONA = ENCIRCLES THE GLANS, IS A
RIM OF TISSUE
=ONE OF MOST EROTICALLY SENSITIVE
AREAS OF PENIS
=The corona and frenulum tend to be the
most erotically sensitive areas of the penis.
,C. FRENULUM = ON UNDERSIDE OF PENIS,
THE CORONA MOVES IN CLOSER TO THE TIP
OF THE PENIS, CREATING A STRIP OF LOOSER
SKIN CALLED THE FRENULUM
=ONE OF MOST EROTICALLY SENSITIVE
AREAS OF PENIS
=The corona and frenulum tend to be the
most erotically sensitive areas of the penis.
D. FORESKIN = A LOOSE FOLD OF SKIN THAT
PARTIALLY COVERS THE GLANS IN AN
UNCIRCUMCISED PENIS
-IN CHILDREN: FORESKIN SOMETIMES
EXTENDS WELL PAST TIP OF GLANS & ACTS
AS AN EXTENSION OF THE URETHRA
ALLOWING URINE TO PASS THROUGH
-IN MATURE ADULT MALES: FORESKIN CAN BE
EASILY PULLED BACK TO EXPOSE THE GLANS
& NATURALLY RETRACTS DURING AN
ERECTION
E. CIRCUMCISION = SURGICAL REMOVAL OF
THE FORESKIN FROM THE PENIS, EXPOSING
THE GLANS
F. HEALTH BENEFITS OF CIRCUMCISION:
, -LOWER RATES OF STIs FROM VAGINAL SEX:
HIV!! (50%-60%), HPV!! (30%, aka virus that
causes cervical cancer), HSV!! (45%)
-LOWER RATES OF HERPES
-LOWER RATES OF PROSTATE CANCER
-LOWER RATES OF URINARY TRACT
INFECTIONS (UTIs) + INFANTILE URINARY
TRACT INFECTIONS
=NO EVIDENCE THAT CIRCUMCISION
PROTECTS FEMALES

THESE LIE ON EITHER SIDE OF THE PENIS,
HARDENS DURING AROUSAL//STIFFENS
DURING ERECTION
