Grinding

I discovered masturbation when I was about 13, I was looking at some porn on the internet and I was grinding against the arm of the computer chair, since then I have now moved on to the edge of the sink. Simply put out about two towels on the edge of the sink and keep your pants on (can be sore if you dont!!). After about two minutes of rocking back and forward you will cum so hard you'll see stars!!

Give it a go it works wonders!
