The erectile tissue is composed of many tiny blood vessels arranged in random coils. The penis is capped with a pink, acorn shaped tip called the glans. A sleeve of skin, the foreskin, naturally covers the glans but is sometimes removed in an operation called circumcision.
A nice technique to set the mood for cunnilingus is to lightly massage the area between the navel and the pubic hair with the tip of one index finger for a few minutes. Put a few drops of glycerine (purchase at drug store) on her belly and massage into the skin with slow, small circular motions. You should warm the glycerine before applying it to her skin (place the bottle in hot water for a minute). This massage technique tends to relax and sooth the woman and is especially good for the first time she experiences cunnilingus.
The man can place his hands lightly on the back of the woman’s head to provide guidance. Lightly stroking the woman’s ear or earlobe with the forefinger can provide stimulation for the woman. Try massaging her forehead; run your thumbs from the center of her forehead outward, ending at the temples with a small circular stroke. Repeat.
