The woman begins by kissing and caressing the penis along its entire length, as well as the testicles. When the penis is erect, she grasps it firmly and begins vertical regular movements, by squeezing slightly during the ascent and by loosening it in the descent, taking care near the tip, which is very sensitive. The man can guide    her hand, to show her the best rhythm and the amplitude that he prefers.      She can alternate long caresses along the length of the penis with others more concentrated along the tip. To facilitate the movement, and avoid any      pain, it is advisable to add a little saliva, either by the woman placing the penis in her mouth to moisten it, or by adding saliva to her hand .
