OK, one word for you if you want larger ejaculations: MACA. I remember shooting so much that the girl needed to go for kleenex and STILL I had to go to the bathroom and wash it away. I know, graphic! But thats the "magic" of the internet, when truth can be raw. However, Maca its stimulating and if you have sleep issues it can be bad. I would try and see. It also increases desire, focus and erections mildly and improves antioxidant status. Its definetely in my book of aphrodisiacs for the future. Other things like royal jelly or swedish flower pollen are said to increase semen quantity.
