Tight Sack??

[horndog]

i was wondering why when i stand up my sack is usually pretty tight up but when i am sittiin and relaxed it hangs again. my only problem with this is when im standing it makes me look like my balls are small but when im sittin and they sack is loose they look big again. im just wonderin if this is due to stress or maybe my horrible diet with little water. im leaning toward stress and bein up tight but let me know what u think doc.

Its normal. Its all about temperature control. As I understand it, the testes produce sperm at a slightly lower temperature than the rest of the body. That's why they are in a scrotum, so the temperature can be regulated. When they hang, the body is just relaxing certain muscles in the scrotum so that the testes are further from the rest of the body, which reduces their temperature slightly. (I think that is right, but I'll defer to any medical experts reading this.)

This is temperature related. Sperm develops and lives best at a specific temperature so the sack is designed to keep them closer when chilled and let them hang away when warm. Cyclefreak is correct.
