yeast infections and my boyfriend ?

so this may sound like a naive and stupid question but i honestly had no idea it was possible.

i think i gave my boyfriend a yeast infection. im 99% sure i have one and we had sex (twice) for the first time in a long time. (cause i haven't been feeling it in my last trimester) then last night he came to me and said he was itchy and has this redish rash on the tip. he is also uncircumcised if that makes a difference.

does anyone know if men can get yeast infections from their partner and what they can do to get rid of them? anything at a local drug store?
