Lots of topics stewing in this thread. As for cum volume, I take 25 mg of Zinc Picolinate daily (ostensibly for the benefit to my prostate gland) and 500 mg of L-Argenine. Have been doing this for almost a year and have notices a substantial increase in seminal volume although it is somewhat more watery than before I started with the supplements.
In search of the "massive" load I tried a product called Maca--it's a Peruvian radish. I went with the powdered "gold". It tastes like shit, but can be disguised in a protein shake or in juice well enough to suck it down. It took about 10 days before I saw an amazing increase both in pre-cum and my orgasmic load. With a little stimulation pre-cum actually drips from my cock and (especially if I haven't cum for a day or two) when I cum there is 2 or 3 tablespoons as opposed to one (maybe) before the Maca. For me, the stuff works.
As for strength and distance, well, I am getting older and can't splatter the wall half-way to the ceiling like when I was a 20-something. But, again, before the supplements I would have a modest spurt or two and some oozing but after have 4 or 5 strong shots and then the ooze.
And, as everyone else says, the amount of time between orgasms makes a big difference, as does hydration, limiting alcohol and, honestly, the degree of arousal. Being really turned on probably does more for volume and stamina than anything else.
One thing that age has improved is stamina. I think it's a trade off. In your twenties you cum fast and recover fast... later in life you can make love for an hour but then (usually) have to wait quite a few before going at it again. As they say, built for comfort not for speed. I--and the women I'm with--generally prefer long slow loving to wham-bam, thank you m'am.
Add it all thogether and I can kind-of pretend I'm a young stud again :biggrin1:
