What Causes Small Raised Patch With Fluid Sacs And Itchiness In Penis?

My boyfriend is experiencing a penis issue. His penile shaft has a small raised patch of skin with three tiny clear fluid sacs. They dont burn, he has no fever, no trouble urinating, but he says they itch like crazy. They healed. Three days later, he has the same thing, just in a different spot on his penile shaft. I have had a yeast infection, and we had been gaving sex regularly. He says they only itch, that they dont hurt or anything else.
