Well, I don't know where to begin from. When I was really young, just 12, I discovered this thing that made me happy when touching my dick.
This was a way I started my masturbating phase. First of all I had no hairs and so made this masturbation easier.
Strip completely for better results, lie face down on the bed or on something warm such as a carpet. Then just stroke yourself from side to side thus rolling your dick between the bed and the belly. For better performance hold on the sides of the bed with your hands (so you must have a single-bed).
After some time you will come.
1. Shave well your penis because due to the continuous rolling you may trap some hair and this may hurt.
2. PUT A TOWEL UNDERNEATH YOUR DICK because if you do not succeed in turning face-up before you come, you will mess up your bed and if your family does not tolerate masturbating, you will end up in some trouble (talking from the tennage point of view).
Good time masturbating.
