There are two ways to make love (i.e. sex) to or rather with a man. You can fuck with him or you can make love to his genitalia. In the first case you want him as a whole being, that´d be a full body / full impact affair. In the latter case you want his dick and his balls and his juice. And you want him to go wild over what you do with his sexual plumbing. I want to talk about this kind of lovemaking.
You go for this kind of sex for two reasons. One concerns your man and one yourself. You want to do it for your man, because you can give him the most intense sexual climaxes he may be able to experience. They include deeply felt orgasms and extended ejaculations and everything in between. This provided he has a 100% trust in you and will devote himself fully to your ability to love his genitals with utmost refinement. It requires good communication skills and you gain best results if you not only just know, but love each other.
