Good day, my partner and I have been tested std free recently. During unprotected sex (I am on the pill), after he ejaculates inside of me about half hour later I started feeling numbness in my feet, inability to breathe properly , little bleeding, minor chest pains, feeling as if I want to vomit, severe burning around and inside my vagina and great abdominal pain. It has happened all the three times he ejaculates inside me only. Could this be an allergy?
