He proposed that women have a sensitive spot in the vagina three to five centimeters from the opening that is said to be sexually pleasing for women when stimulated.

However, only a small percentage of women claim to orgasm from the G Spot only.

Their studies branched orgasms out into two different types: the uterine (which was dubbed later by Josephine and Irving Singer) and the vulval.

The uterine orgasm is marked by rapid, gasping breathing as climax is approached.

In the vulval, stimulation of the clitoris is the main method to obtain orgasm.
