How to ejaculate a truly massive load
It seems that you need some assistance! I consider it my duty to help you on the road to grand ejaculation.
1. DRINK WATER. Two tall glasses of clear, cold tap water. At least TWO hours before any action.
2. This is a differential one. (A) If you are fapping, fap for an hour, rest a minute and drink another glass of water. Then fap for another hour. (B) Although unlikely, you might find yourself in a sexual situation with another human being. The key here is FOREPLAY. Get her/his excited, and let yourself get excited, but take it slowly and smoothly for maximum pressure when the time comes.
3. Dietary stuff. Celery is VERY good, but that much celery all at once can mess up your stomach. Drink a glass of milk before binging, but start slowly with your new diet. Easy does it. Pineapple is also pretty neat. The key to volume is not only fluids, but also minerals. Zinc is the solution! Zinc is pretty prominent in things mentioned above (probably. I am not a dietist, I am a pedoatrician.) and guess what is chock-full of Zinc? Spinach. If you feel that this is not enough, take about 40 mg zinc a day, in pill form. Upper limit is 50, but consider the fact that you're shoving yourself full of celery and spinach as well.
4. Physical exercise. Although you might hate it, being fit is good for the WHOLE body. Start doing Kegels.
