My Boyfriend Experienced Discomfort With Sex And Difficulty Pulling Back

My boyfriend experienced discomfort with sex and difficulty pulling back the foreskin. Then, his Penis started to slightly itch. Then, he got 11 or so little red dots near the bottom of his penis head and on the inner foreskin. I gave him monistat cream to help and the little red dots went away. The next day, they were back only this time they were white. Today, they are back and red again. What is this and what should we do?
