Psychological Aspects of Human Sexuality
Female Sexual Organs
● Classified into two categories:
o External organs
o Internal organs
● Female external organs
o The vulva
▪ Mon pubis – fatty tissue covered in pubic hair.
▪ Clitoris – sensitive to sexual stimulation.
▪ Inner lips – sensitive to touch. More of a mucus type of membrane.
▪ Opening of urethra – sensitive, highly vascularized.
o The clitoris
▪ The majority of it is the internal structure.
▪ You can only see the glans when you pull of the clitoral hood.
▪ The corpus cavenous bodies engorge with blood when aroused.
▪ Stibular bulb (bulbs of the clitoris): underneath the cavernous bodies, surrounds
the urethra and vagina. They are veins that become engorged with blood when
there is sexual stimulation, making them very sensitive.
● Various types of hymens
o Thin flexible tissue that is located at the entrance of the vagina, partially covering it.
o It is hypothesized to protect the vagina from infection when the baby is born.
o Hymens are not a good indicator of virginity.
o There are a lot of variations.
o They can tear if you do a non-sexual activity, such as horseback riding.
o Some are born without one.
o Myth that when torn it will bleed and be painful.
▪ Pain actually comes from pelvic floor muscle.
▪ When a woman has her first sexual experience there is a little nervousness which
causes her body to tense up, including the pelvic floor muscle. Friction can be
very uncomfortable. Also that nervousness, can impede natural lubrication,
meaning the friction can cause bleeding.
● Female internal sexual and reproductive organs
▪ It is divided into thirds.
▪ The first third is highly innervated and vascularized.
▪ The back 2/3 have very few tactile nerves.
▪ The vagina is about 10cm in length, but becomes longer and wider when aroused.
▪ The ph in the vagina is acidic. The ph is very delicate, any bacterial or yeast
overgrowth can create infections.
