I am 19 years of age and I've masturbated since I was 12/13 and I've tried a lot of ways to do it, here are some, all actually.
The first time I masturbated, was by tickling myself (my dick) it really sent tingly feelings all over my body until at one point I came. However it doesn't stimulate me anymore because it takes a long time and my dick is not as sensitive as it used to be.
You know the movement you make when you are trying to light a fire by using your hand and a twig. Well that is a good way to jack-off as well. In fact it was one of my earliest masturbation methods. It is relatively simple and is really quick, if you are in a hurry lol. you just put some soap (or any kind of lube) on your cock and rub.
Another way is to put vaseline on your cock, the head especially. and then pull on your cock from top to bottom as if you are pulling on a rope. mix the vaseline with a dash of soap and water so you can reduce friction. You reach incredible orgasms but if you do it a lot it is really dangerous because there is so much friction. I have only done it 3/4 times in my life.
A good way to stimulate the head is to wrap your fingers around it and caress it. This technique comes in handy when you have a blister on a part of the body, because you don't need to use the rest of your body to get an orgasm.
Use of precum is also good since it sprays all around the head you can just wrap your fingers around the head and just rub there, natural lube I like to call it.
Then there is the classic "wrap your hand around your dick and stroke" Up and down but everyone knows that.
Hope you try some of these and feel free to add some of yours.
