This Wednesday I had asked on Facebook is anyone had any questions about sex and/or marriage, since I hadn’t gotten an anonymous question in a couple of weeks.
Then one of my regular readers and participator sent me this question (among others):
Why the shakes and spasms after orgasm?
That sounded like it might have a fun and interesting physiological cause, so I thought I’d tackle it today.
Many women find that they shake, or have spasms after orgasm. For some, it’s slight, for other’s it’s almost a flailing of limbs, and their husband better watch out. I’m afraid I can’t find any stats to say how many experience this, but judging by the amount of people asking, I don’t think it’s that rare.
As far as I can tell, there seem to be two prevailing theories and/or causes.
Trembling is a sign of a highly increases heart rate
The first is that people often tremble when their heart rate increases radically. This is most well known when someone is scared. When we’re scared our hearts start pumping more blood to help us get more energy to our limbs, to run away or to fight, to our senses, so we can see better, hear better. Basically, it’s a response designed to help us avoid danger.
Now, during sex we aren’t in danger (hopefully), but we do tend to have an elevated heart rate. Some people’s heart rates increase more than others, and it seems that for some women, it raises so high, it gives the same tremble, thanks to all the natural chemicals being pumped into our blood stream along with the increases heart rate.
So, one way to test this theory would be to check your heart rate (when you regain control of your limbs). If it’s really high, that might be your reason.
It might be caused by spasming muscles due to prolonged tension
Many women find that they need to clench muscles in order to have an orgasm. This is what leads to grasping bedsheets, raking fingernails, puling hair, etc.. One common muscle to contract is the thigh muscles. In fact, they can be so tense that they should cause pain, except that you are being fed so many natural pain relief hormones that you don’t notice it.
Then, when you do orgasm, you finally let go of the muscle tension, and your legs have been under such high tension for so long, that they start to shake simply from the workout.
Want to check this theory? Check to see if your thigh muscles are contracted during sex. If they’re hard as a rock, that’s probably what’s going on.
So, there you go. Two reasons why you might shake after you have an orgasm.
