You could be suffering from motion-sickness.. I know how funny that sounds but it really could be that.
There is a tablet called buccastem that cuts of the "feeling sick" signal from he brain you could have the worst sickness hangover known to man and STILL not feel sick after taking one (I know I've used them often enough!) You need to talk to your doctor I'm afraid
I used to be exactly the same way. I'm not sure what the cause is. I've read a lot about spiritual sexuality and buddhist, taoist, etc. practices, and I've learned that they believe that sex is a fulfillment within your body, and if you're not fully satisfied, then there is a lingering that makes you physically ill. So I started paying more attention to me and getting more out of sex. It seems to have helped, I don't feel sick afterwards anymore.
I get that way too! It usually only lasts a couple minutes...maybe 15 min. I always assumed it was like motion sickness.
