Very little. Only 3-5% of the total semen fluid is produced in the testicles. The rest comes mostly from the prostate and the seminal vesicles.I have always wondered though, if your ball size is directly related to your cum production.
I don't think your balls are especially small. I've personally felt balls that weren't much larger than seedless grapes. Your dick is huge. Maybe your balls seem smaller to you in comparison to your dick.I posted this in another thread but I have small balls. I didn't even realize people even cared about the size of there balls till I visited this site lol. I thought it was all about dick size...unfortunately my balls don't compare to the size of other's on this site.
Yeah, you don't want to inadvertently flush your balls down the toilet. :biggrin1:So those of us that occationally tea bag ourselves on the toilet need to be careful of the flush as we age hahaha
