If you want to increase the amount of cum, take lecithin and zinc with your meals. Especially the lecithin.
When you open the tub of lecithin granules and take a sniff, you'll recognise the smell immediately and then you'll know why it's so good for you !!!
It really does work wonders. I put two large spoons on my cereal every morning to help my cholesterol. I don't ejaculate too often as I prefer to conserve my resources for more fun, but when I do I fire off about twenty rounds before I'm done.
Watch the Zn though, not to overdose, but if you're firing often then I guess you can take a little extra.
Yes, you need to watch the amount of zinc. Usually 50 mgs a day is okay.
