Every man needs to have this skill if they are interested in bringing their lady to a higher level on the satisfaction scale.
Although, I found that this writer uses unnecessary slang vocabulary (some may consider it, somewhat, vulgar) and can easily offend if you linger too long on the words, if you can look past that, the points are descriptive and excellent. For those men that have never been quite sure what to do down there, this will help tremendously and for those women that are still trying to figure out what they like and how they like it, this will help you in directing your man to try some things. Most guys actually like being directed because it turns them on when they know they have turned you on. How simple it is to please….
