Drink lots of water! And also what will produce a lot is abstaining from sex for at least 3 days, gives your body a chance to produce and make a store of it in your body. But what will make you produce the most is stimulation, the longer you have sex and are aroused the more you make, that simple. If you have trouble lasting just do what I do, when you get to the brink just pull out and give yourself a chance to rest it, this can be the time to give your partner please during this rest period, that Way you both benefit, she gets pleasure and you get a rest, when you've calmed down a little go again, just keep doing it til your tired of it, the results are usually mind blowing in my case. Hope this helps!
