Hi,

The testicles are a man's sperm production "factory". The two require an "operating temperature" a couple of degrees lower than his core temperature. This is why they are hanging outside and not inside the abdominal cavity.

Because the ambient temperature changes periodically, the scrotum is designed to snuggle up tight against the body in order to acquire additional heat. They are also designed to slacken and dangle away from the body in order not to be so hot and be above optimum operating temperature. So, depending upon the temperature within his clothing, and/or outside in a room or out of doors, the scrotum will change from dangling to tight as well as in between, and, could be in a constant state of change--depending.

In order to change size, the skin has the ability to tighten up, as a result becoming very wrinkly. At the opposite extreme it slackens and becomes very elongated, loose and soft.

I got sidetracked and forgot to answer your second question.

The testicles and sack are two different entities. Visualize a paper bag with two oranges inside. The sack is only the container having the ability to change its length in order to bring its contents closer of farther away from the body's heat.

Feel the sack. Feel the two testicles within.

If you want, after he becomes very very aroused, scratch the scrotum using a come-here motion of your fingers. You can also knead the skin by gently pinching a piece between two fingers and massaging it. Both feel very good at such times.
