A good way is using something like a toothbrush handle, a thick marker, or hairbrush handle and wrapping it in a condom as a dildo. Another way is putting a wet heavy blanket in a washing machine and turning it on to spin only cycle. It will vibrate a lot, lie backwards on top of it and it may feel good. Some strange ways can be using a vibrating cell phone and vibrating through your clothes. There are really tons of ways, just get creative. Sign In.
Page 1 of Lie down on your side and hold onto your penis with the "Backhand" grip. Roll over further and brace your hand against the bed, and thrust your penis in and out of your hand.

It's a single piece of neoprene foam rubber, not the slitted foam-plastic type others have suggested here. Cut a length 3" longer than your erect penis. With sandpaper, roughen 1" of the inside at one end, apply a 2-part epoxy cement, and clamp it shut with with the other open end pointing up. After 12 hours remove and install around the rubber sleeve two thick rubber bands at 1" and 4" from the open end. The rubber bands they use to tie fresh broccoli are best.
My year-old high-school self is here to help you out. This is something I've wanted to write up for the good of teen boys everywhere for like, the last 20 years or so. If you've got a condom, you can make a pretty good masturbator with some of the stuff around the house, or better yet, a few bucks at a hardware store.
