Do G-spots really exist? Well, don't get into such questions. Your man's body has some areas which are really sensitive. Stimulating those points will make him scream in pleasure.
The male G-spot is said to exist somewhere near the anus. Stimulating it isn't tough if you don't mind to go the extra mile for your man!
But wait, before trying this, you need to ensure proper hygiene. It is better if you and your partner go for a shower to wash each other well.
If you have gloves, wear them. If you don't have gloves, cut your finger nails short as you are going to use your fingers in sensitive areas.
Firstly, touch your man's penis and move it down his balls. Keep it there for a few minutes and gradually move it till the anus.
Move your finger gently around the anal area and see his reactions. Keep moving your fingers gently between his balls and anus.
If he is enjoying your efforts, use your tongue to lick the area between his balls and butt hole.
If he feels good and requests you to insert your finger inside his back, tell him that he is expecting too much from you! Well, jokes apart, it is not safe to use your tongue too much in the anal area. So, enjoy within the limits to stay healthy!
