Point A: recently discovered, located between the G point and the cervix. It can be stimulated directly or by rubbing the vaginal wall. During sexual intercourse, try to sit on the bed and let your partner enter from the front.
G-spot: Griffinberg first noticed this position at 1944, but it was not until 1982 that the G-spot was widely known through the promotion of a bestseller. It is a pea-shaped area about 5 cm at the vaginal entrance. The best way to stimulate the G-spot is to take a female posture and let your partner enter from the post-test.
It's on top of the woman. Pay attention to her face after touching. Generally speaking, women there are very sensitive. Touch it right and you'll know.
U point: about 2.5 cm at the vaginal entrance. People often confuse it with the G-spot. The stimulation of point u will make you want to pee. When U-point stimulation is combined with clitoral stimulation, the effect will be better.
