for those that are interested, there is a muscle that runs down next to the spermatic cord and vessels to the testicle. Thereā€™s one for each testicle. The muscle is called the cremaster (I guess this is latin for something or other - I should also admit that this is from my knowledge of animal anatomy as a vet though I presume itā€™s the same for humans) and is the one responsible for pulling the testicles up or letting them down. ---

It works! I canā€™t really control them, yet, but I can make them go faster. Yes, Iā€™m easily amused. Iā€™ll keep you updated on my progress. ---

[hijack] Not only do the testicles move, but so does the penis. I donā€™t mean getting an erection, either. If you stare at your penis (assuming itā€™s non-erect), youā€™ll see that it expands and contracts, like an inchworm thatā€™s not going anywhere. I know why my balls are moving, but why my penis?

[hijack] My ex used to find mine funny, too. When we were gonig at it pretty good, sheā€™d hop over to the side, throw the sheet over Mr. Happy and tell me to make him jump. That used to entertain her to no end. TMI? Sorry about that. [/hijack] ---

When I was prepubescent, I used to play lots of games with my penis. My two favorites were ā€œhide the peepeeā€ and ā€œwave the peepeeā€. The first involved stuffing the penis up inside the body, so thereā€™s almost nothing sticking out. The other involved contracting my muscles so that my penis would jump up and down. I could do it in time with music. At the tender age of 11, I made the mistake of showing off my skills to my two younger sisters (I never did have any shame). They shrieked with laughter, and ran around the neighborhood telling everybodyā€¦ I still get reminded of that from time to time. ---

Each and every one of you guys is guilty of Heresy. Of course testicles donā€™t move. Everyone knows that testicles remain fixed and the universe moves around them. Geez. ---

Q: How many testicles does it take to change a lightbulb? A: One Pair. They just hold the lightbulb and the world revolves around them. Sorry, Manny, I had to. šŸ™‚ ---

I was waiting for this to load and re-read the OP. Cisco actually says ā€œHave you ever looked intently at your testicles for any amount of time?ā€. Sorry, but this strikes me as really funny. Cisco setting around staring INTENTLY at his balls. :snort: :giggle: BWAHAAHAA!!! Sorry, man, really, no offense meant. Honest. But the mental imageā€¦ Damn, now I forgot what I was going to post.

Oh, yeah: Q: How do you tell if a girl is ticklish? A: Give her a couple of test tickles! Now Iā€™m leaving to stare intently at my balls. Hey, do we need a special smiley for this? I could see it coming in handy like when someone is apparently not paying attention or is distracted. Just donā€™t name it after me! ---

I all for the smiley idea. It could be a smiley sitting at 270 degrees with a confused look on itā€™s face. :testiclestare: ---

So if youā€™re really hot, ( no snide comments) they descend to cool off and if youā€™re really cold, they snuggle up to stay warm. \\*\* Why do they shrink or tighten up right before ejaculation? Thatā€™s the only time Iā€™ve noticed that they move, but Iā€™ll definitely have to look into this when I get home and see my husband!
