How I Do It!
When I was younger I didn't use any lubricant when masturbating, but for that last several years I have. I experimented with several things until I stumbled on this Johnsons & Johnsons lotion with baby oil. It feels great, is slippery, and lasts quite a while too. It's also cheap and easy to find. I just apply a little lotion to my cock and stroke away. Sometimes I'll watch a video or look at a magazine.
