Here's what I do(if it's just Me, Myself, and Vaseline). If at all possible I don't cum for a couple of days. Then I start off by watching a lot of just kinda hot videos to get me going(something like girls dancing on Youtube) after a while I find a good video to jerk it to and I jsut slowly build it up. I'll go fast and slow to mix things up. I'll get myself to where I am just about to cum and stop. I do that for about 30 minutes or so but the longer you can wait the better. Once I'm ready to blow I slowly build it up. Don't go whacking away at it. Take your time. Now here comes the tricky part that is a little hard to explain. I jerk until I am about to bust and I stop, grab the base of my dick, and I make it jump(kinda like stopping yourself while peeing). After every burst(usually 5-6) I give it a couple of quick strokes and grab the base again. I started doing this about 3 years ago. Not only does it make your orgasms 100 times better, it is much more impressive to your partner. If I am really feeling it and take my time I can easily get 3-4 shots over my head(lying on my back) and usually if I just get a quick 10-15 minute jerk I can get one over my head. I'm not sure it is a bigger load per se but it will increase your distance and you'll have more shots. Plus it feels soooo much better. I'm still trying to figure out how to get the thickness of cum like Peter North does but that may jsut be something that is individual to the person.
