Sperm Volume

You mean ejaculation volume? Sperm and ejaculate are different. You actually SEE the ejaculation. Anyways, I don't technically have an answer to your question, but from one guy to another ... I happen to be a person that ejaculates a very high amount (had to turn in a sample to the Doctor as the wife couldn't get pregnant). Anyways, so that's how I learned my amount of 28cc. FYI, the avg. is 1cc-5cc. 28cc is crazy, but I've always produced a lot. I can share with you that I've always gotten hard and then soft again without ejaculating. I've heard that can build it up. Also, your prostate is what controls it, NOT your testicles. I think we're all just wired one way or another, kinda like allergies. You either have them or you don't. If it helps, I've only had just a few girls be like WTF when I cum. Most of the time, they don't even care. Only in porns. In fact, it I've ruined a few girls outfits as it does bleach ya know.
