The clitoris is located above the vaginal canal. It is not always noticeable. It is pink skin beneath an inverted V.
Within the vaginal canal there is a patch of ribbing along the front of the canal. It feels something like the palate (the roof of tour mouth). This is the G-spot.
At the end of the vaginal canal is the cervix. With a female lying on her back it will be in the direction of her tailbone. It feels like a scallop (I'm sorry for the image). It can be extremely pleasurable. Unfortunately it is located very deep inside the woman. It may be necessary to insert a finger to the knuckle to reach the cervix.
A very good sensation can be achieved if two fingers are inserted. The middle finger touching the cervix, the index finger touching the G-spot. The thumb stroking the clitoris. For an alternative use ones mouth against the clitoris and hum.
