My favorite way to mastubate is to go slow. I sometimes take a couple of hours. I like to look at porn and read storys while masturbating(I'm actually masturbating right now as I write). I like to get completely naked and bring myself right to the edge of having an orgasm. Then I stop for a litle while and slowly bring myself to the edge again. I get myself to the point where I just feel my penis start to pump. It feels incredible doing this over and over. When you finally orgasm it will be so powerfull and breathtaking. I squirt so much cum out.
While I'm masturbating I frequently rub just the tip of my penis. This gives me some of the most pleasureable feelings. I can rub my finger across the opening of my penis for a long time and it sends continuos waves of pleasure through my body. The great thing with rubing the tip of the penis is you can rub it and it feels really good, but it doesn't bring you to a quick orgasm. Just great extended pleasure.
