G-Spot
The G-spot: some think it’s a myth; others are convinced that it’s not only real, but it’s also highly effective in triggering mind-blowing female orgasms. While the scientific community may still be divided on the G-spot’s existence, ask any woman who has had a G-spot orgasm, and she’ll tell you that it’s definitely there, and she wants you to stimulate it.
Locating the G-spot can be an epic quest. It can be remarkably easy to find in some women, while in others it’s almost impossible.
Different sexual positions stimulate women differently, therefore, from the positions listed below, in what position have you had the mind-blowing orgasm?
Doggy
Rear-entry positions are some of the most reliable when it comes to stimulating the G-spot during intercourse. You can try it doggy style or in the spooning position for a more relaxed option. In order to have the greatest chance of success with a rear-entry position, your cock should rub against the front wall of the PU**Y. You can try lifting her hips a little and thrusting in a downward motion to perfect this G-spot position.
CG
Many women prefer positions in which they are on top. This probably has a lot to do with the fact that when she’s on top, she’s in control. Woman-on-top positions, like cowgirl and its variations, are great for hitting the G-spot because the woman can angle her hips just right, allowing her to find the arrangement that feels best to her. She can try leaning forward or back while adjusting the speed and pressure applied to the G-spot.
The right rotation
Rotated Woman is a tantric sex position that is excellent for stimulating the G-spot. Start by lying flat on your back with her straddling you, facing away. Then she should carefully lean down until she can grab your ankles and is lying on top of you. Once in position, she can move up and down or circle her hips in a figure-8 pattern. The angle makes her vagina tighten up, so the rubbing of the penis provides intense G-spot pleasure. She may also get some clitoral stimulation in this position, so she can have the best of both worlds.
Heels over head
Positions in which her feet are on your chest or shoulders are also great G-spot positions. In tantra, this position is referred to as The Flower Press. Start off like you would if you were using the missionary position, then once you have penetrated her, she should lift her legs up and back until they are pressed against your chest or over your shoulders. You can lean against her thighs for support while she grabs your hips and brings you closer for maximum penetration. This G-spot position works because of the angle of the penis as it enters and the depth it can reach.
