I Have A Difficult Question. I Am An Older Woman,

I have a difficult question. I am an older woman, with several non contagious health conditions, and I have a boy friend also older. He has been battling an itchy red rash on his chest and back, which he has been told is
an allergic reaction, not contagious. He says he wants sex, and has seemed annoyed with me for asking him to
hold off until he is healed completely and not using the steroidal cremes and pills for awhile. Am I correct in being cautious. He had suffered so much the itch kept him awake. Please advise me. YYYY@YYYY
