I have to disagree with one of the posters above. Celery does increase semen volume. It does more than just alter the taste. You have to eat as much of it as you can and wait at least one day. The celery must be eaten raw and fresh. I don't care for the taste of celery so I dip mine in "All Seasons" Blue Cheese dressing. Otherwise I probably couldn't deal with it. Other things you can try are tribulus, l-arginine, bee pollen, fenugreek, and saw palmeto. L-arginine provides the body with a necessary amino acid to produce more semen. Tribulus stimulates cells in the testicles. Bee pollen provides some trace elements and improves prostate function which helps it to produce more fluids to contribute to semen. Saw palmetto also enhances prostate function. I am not exactly sure how Fenugreek works, but it greatly increases semen volume. I take it. Even if you nut every day, your volume stays consistent and larger than normal. Taking large amounts of it a day or so before a "special event" can really give you a healthy sized load. I think it acts by affecting hormones. Another added benefit of Fenugreek is like Tribulus it helps the body produce more male horomones. L-Argnine seems to give you that really thick glue like cum. But be careful with L-arginine. If you have a healthy erection already, L-arginine can cause your body to overproduce nitric oxide. This sounds like a good thing since nitric oxide leads to erections, but then the body will normally try to counteract this by reducing the levels which could lead to diminished erections. If this does happen, stop taking the l-arginine and give your body at least 2 weeks to return to a balanced state. I have experienced this problem with L-arginine which is why I do not take it currently. But I do take the bee pollen, saw palmetto, fenugreek, and tribulus and they all work great. Make sure you take breaks with the tribulus and fenugreek. I do 5 days on and 2 days off and that seems to work great. Also be prepared that Tribulus and Fenugreek both can cause your skin to become oilier. This may become bothersome for some, but is also a sign that the supplements are indeed working. Large amounts of controlled realeased b5 can reduce the oily skin.
But no supplement can turn you into a shooter. Shooting semen is more about muscle contraction than volume. Like other posters have said, strengthening your pelvic muscles could help. But nothing influences a good cumshot more than intense and extended arousal. So take the supplements, drink plenty of water, exercise your pelvic muslces, find you a really hot date, and delay your ejaculation for as long as possible. If after doing all these things, you still find your cumshot less than adequate, you may need to visit a urologist. Something might be amiss with your prostate or testicles. There could also be some sort of hormone imbalance. For some reason a lot of guys even young ones are dealing with this now.
