Think I saw someone mention on Thunder's (no source), ejaculate volume is: ~85% seminal vesicles, ~12% testicles (sperm), ~3% is cowper's gland. The idea was that big testicles do not equal big loads since the vast majority is not from the testes. I used to shoot huge, clear loads (7-12 heavy ropes, always at minimum 7 then up to 12 depending on circumstances, maybe a time or two I hit 14-15, but usually the majority of the volume was just larger in the first 7 ropes) that would spatter and cover intermittently the whole torso of whoever I unloaded on (largest cumshot was from edging for an hour or so and the central load was a full, unbroken pool/puddle a few inches larger in diameter than a basketball, lots of spatter outside of that too, this was about twice the average of the above mentioned...and we're talking "upon landing", not thinning out over the following minutes and spreading). Since then over time they've gotten creamier, whiter and thicker and are a lot less volume but I've still gotten lots of comments about how my loads are still markedly larger than whoever else they're used to seeing (but they don't impress me or even seem all that large, maybe 30-50% the footprint of a XL size hand).
