There are two types of orgasms: clitoral orgasm and vaginal (also called G-spot orgasm). The first is achieved through stimulation of the clitoris and the latter is attained through stimulation of the G-spot.
The G-spot is located about an inch inside the vagina. Both the clitoris and the G-spot can be stimulated during intercourse and foreplay. The clitoris gets stimulated by the vaginal wall which goes back and forth during intercourse.
The arousability of the clitoris and the G-spot depend to a large extent how good blood circulation is in the pelvic area and how strong your pelvic floor muscle is. |
Basically the better shape your pelvic floor muscle is in the easier it will be to get stimulation, because muscles that are in shape need more blood going through them - which increases sensitivity and arousability for both the G-spot and the clitoris. Secondly and espescially for the clitoris, a strong pelvic floor muscle increases direct stimulation.
