Several years ago, I took Maca made by Soloray and available at Whole Foods. It is also available online.
With that I took about 6 grams of powdered L Arginine available in bulk from online pharmacies. (I buy mine in 1000 gram jugs from
www.beyondacentury.com)
These two things together increased my ejaculate just like you say ............more volume equals more spurts and more spurts/ropes are very pleasurable. I snorted like a Brahma Bull during orgasm.
Alas. I ran out of the maca and should be thinking now of getting more. It took about two weeks to notice good improvement in ejaculate volume. An on line friend buys his maca in bulk at cheap prices from Peru, I believe, where it is grown.
