question: SOME TIMES DURING SEX i GET AN EXTREAM BURNING SENSATION JUST BEFORE I EJACULATE... ESPECIALLY WHEN MY WIFE SITS ON TOP WITH BACK TOWARDS ME... I HAVE NEVER HAD SEX WITH ANY ONE ELSE EXCEPT MY WIFE IN 40 YEARS THIS HAS OCCURED IN LAST 8-10 YEARS BUT MORE AND MORE OFTEN NOW... IS THIS A SIGN OF CALMIDIA ... THAT SHE MIGHT HAVE CONTACTED AND TRANSMITTED TO ME...??? EMBARASING TO ASK HOW REDICULOUS AFTER 40 YEARS OF MARIAGE TO SUSPECT SUCH A THING... SHE OFTEN HAS A VERY STRONG ODER THAT SHE LEAVES ON ME AFTER SEX THANK YOU
