Did u notice the connection between how often/rarely u cum and how big/heavy/low hanging your testicles are? If u cum rarely, there must be an increase in size, because the production of sperm is constant, and testicles have to adjust their size to the amount of the liqiud inside. How do u think mates?
no, not at all, allways had neat small testicles and they don't increase in size to my knolage even if i havent cum for 2 week's or more.
Most of the volume of semen is made up by the seminal vesicle, which is next to your prostate. Tescitcles have rather little to do with volume. ALthough they produce testosterone, which may (im not sure) effect ejaculation frequency and libido.
