Yes there is always a reason. I think there might be something wrong with your stomach's function. Eat the haw everyday might be help. Good luck!
6 weeks ago started vomiting, still going on. No fever no pains
There's always a reason.... Sit back and evaluate what's going on with your body, what you've put into it and possible other symptoms. Are there other symptoms? Do you have a fever? Is it possible that you're pregnant?
I usally vomit after a very intense anal session. Or ingesting the feces attached to the end of his penis as I perform after anal, oral. Then again it could be from the testicle impact that occurs in during certain positions.
