This week's 'question of the week' in Jackinworld.com is about what directions you'd give someone who was about to masturbate you. Interesting question. Here is the answer I sent in.
The first time I had a friend masturbate me, I was too shy to give him directions, and he was too rough on me. I eventually came, but then when I did him, he guided me to make it feel better to him, so I got the point. The next time I told him to slow down and do it more gently, and to concentrate on the part of my penis just below the head where it feels best. Then as I started to feel better and better I told him to speed up and to use shorter strokes. Then when I was about to come I told him to avoid touching the head, as that is too sensitive on me. This time I had a great orgasm, and told him so. He looked pleased. I certainly was! From then on I never hesitated to give directions, but found that after one or two such sessions my friends got the hang of it, and I would seldom have to tell them to do anything differently.
