What Causes Abrasion On Penis After Intercourse?

Question: i WAS JUST TOLD THAT A FRIEND HAD ABRASION ON HIS PENIS AND ASKED ME IF i HAD ANY PROBLEMS WITH A DISEASE. i JUST WENT THROUGH A XXXXXXX SMEAR, TWO ULTRA SOUNDS ON MY OVARIES, i DID HAVE KIDNEY STONES BUT GOT RID OF THEM. DID NOT HAVE INTERCOURSE WITH THIS PERSON WHILE i HAD THE KIDNEY STONES. HE IS AWAY IN CALIFORNIA AND BROUGHT THIS TO MY INTENTION I WAS SO UPSET THAT HE WAS BLAMING ME. HE HAD A COLD SORE AND DID NOT COME OVER FOR A WEEK AND HALF WOULD THIS VIRUS BE STILL IN HIS SYSTEM. I HAVE NOT SEEN HIM FOR TWO WEEKS NOW HE WORKED OUT IN HIS BACK YARD AND DID SOME CLEANING UP WAS HE CAUTIOUS CLEANING HIS HANDS EVEN WHEN HE WENT TO THE BATHROOM. I GOT CLEAR NOTICE FROM MY TEST THAT THERE WAS NO INFECTIONS AND THAT MY TESTS ALL CAME BACK CLEAN. I AM 70 YEARS OLD AND LOST MY HUSBAND A YEAR AND HALF AGO AND MARRIED 50 YEARS HE DIED TWO DAYS AFTER OUR ANNIVERSARY. I HAVE NOT BEEN WITH ANYONE AFTER UNTIL THIS PERSON SINCE JULY OF THIS YEAR. I WAS DEVASTED THAT HE WOULD EVEN ASKED ME THIS QUESTION. I DID HAVE ORAL SEX WITH HIM TWICE BUT I DO NOT THINK THAT IT WOULD CAUSE THE ABRASION ON HIS PENIS. COULD YOU PLEASE SET MY MIND AT EASE OVER THIS. I HAVE GONE THROUGH SEXUAL ABUSE MOST OF MY LIFE AS A CHILD. TO DO THIS JUST BROUGHT ALL THAT UP AND I FEEL LIKE THIS PERSON THREW ME AGAINST THE WALL. I HAVE BEEN UPFRONT WITH HIM IN EVERYWAY BUT TO THROW THIS AT ME NOW. I AM VERY CAREFUL CLEANINESS WISE WE GET ALONG SO WELL AND HE LOST HIS WIFE FOUR YEARS AGO SO WE HAD THINGS IN COMMON. I CANNOT TALK TO HIM IN CALIFORNIA AND HE WILL BE GONE FOUR MONTHS. I AM IN A DILEMMA ON HOW DO I APPROACH THIS SITUATION. tHANK YOU. XXXXXXX
