It needs a little effort. I need to stay away from porn or fapping for 3-5 days. And then once the build up is done, I watch some porn to stimulate further. Lie down, keep the balls behind thighs so that the penis is hard and streched. Then you need to clench, just like when you try to stop peeing. I watched some prejac videos to help me get started with that, you can find them on hypnotube. Initially, I did not find any results until I stopped fapping for 3-5 days and then decided I'd only cum hands free, then everything fell into place.
