I've stumbled onto this site and love it a lot. Figured time to participate.
One thing I just tried when I was so horny I couldn't stand it...I took a shower towel and laid in on the floor of my bedroom...got totally naked and sat on the towel and started masturbating with some lotion. When you get really worked up, kneel on the towel and sit on your heals...then take the lotion and place a little on your anus. Now while stroking move your body to the side so your heel is right on your anus where you put the lotion. Now you can stroke and girate your hips so the heel of your foot rubs your anus. Makes for intense stimulation of your prostate without penetration cuz of your own body weight pressing against it. A fun and messy combination ends up with a great great orgasm. And the towel cleans up the drip'n lotion and then puddle of cum when you're done! =) Happy bounce'n on your heels guys!
