1. Actually, it’s “sperminology”.
2. I’m against experimentation with all sorts of supplements other than a good mulitvitamin, and I think that better health will lead to better body fluid regulation. A bigger load comes from an overall better state of physical health. The main things to consider are:
- Getting a large amount of protein in your diet
- Drinking enough water (about 1 liter per day)
- Getting enough vitamins (taking a quality multivitamin once or twice a day should do it)
- Eating a balanced diet (lots of sweet/acidic fruits and green leafy vegetables)
- Getting lots of physical exercise and rest
- Limiting your ejaculations (that is, jerking it less). Try to masturbate as little as possible (try for a maximum of once a week, if you must masturbate at all).
These things seem to work for me, I’ve noticed a huge increase in the amount I spill over the past few months since I’ve been really serious about health and dietary stuff, might work for you too if you’ve got the patience.
