helppp please

so i think maybe i got a yeast infection from sex i’ve been having like white discharge and it itches every once in awhile but not overly bad. i have had unprotected sex since then and i was wondering how possible

it is for a male

to get one? what should

i do or have him do ? idk if he has symptoms or anything? would it hurt to use monistat even if it’s not an actual yeast infection. i have no other symptoms
