Eros hummingbird technique and sexual position.
The vibrations add a complete new dimension to the experience. This is how it is done:

• This is a technique that both men and women can use, to enhance the experience of oral sex.
• When you want to use this technique, think about a tune you want to hum, & when your partner is already getting excited, you add to this excitement by humming your tune.
• While you do this there has to be a good contact between your mouth & the genitals organs, not just the tip of your tongue, but as much contact as possible. The lower you hum, the better it will feel in general.
• For him (mans): you can give her the most pleasure with humming when you form lips into a little “fish-mouth”, and encircle her clit with your lips. Make full contact and start humming…
• For her (woman): the deeper you are able to take his penis in your mouth, the more pleasure you will give him with the humming tune…
