Testicular movement during sex - is this extraordinary?

Guy's junk does not usually attract my attention in porn videos, but I thought the amount of spontaneous movement of the guy's nuts in this video was extraordinary, no?

You're right! How weird. Cremasterics to the max!

I have a funny story about this sort of thing. I have said more than a few times that I never had sex in the light until I met Doc. While I have seen my male partners naked a lot I never really paid that much attention. Sex was a chore and was not a pleasure at all until I met Doc. With that being said, Doc was the first and only person I have ever really examined and messed around with sexually where I could examine his reaction to sexual stimuli in any detail. I noticed the skin on his balls moving around one time and asked him about it. I love to watch it actually and he explained to me that it was called a cremaster response.

So one night at work one of the other nurses was trying to describe to me that she watched her boyfriends balls move like that and how cool it was. She was asking if it was normal or not and I told her it was and I also thought it was very cool to watch. I had to call Doc and ask him what it was called. I reported back to the girls what Doc said. It was funny that I had to call Doc to ask him. He probably thought it was a weird thing to call him up about, lol.

One of my nursing college room mates who liked to tell about her conquests had a boyfriend who had a similar response. After a while, we all started calling him Cremaster.

LOL Sue, that's very funny. Did he have any idea what it meant?

He found out after a few weeks of us doing that. He actually liked that his girlfriend was giving him advertizing because he got to put more notches on his bedpost. My school was kind of known for massive sleeping around. The two of them eventually broke up.

LOL, that's just to funny. I love it.
