recurring yeast infections after sex

so for the last 2 months i noticed every time i get treated for my yeast infection and me n my bf have sex a day later or 2 i get an yeast infection at this point it’s him who keeps passing it to me, does anyone how i can treat him? it’s been so hard to get in touch with any doctor right now since they all booked til April or May and I indeed did talk to him about this telling him i think it’s him that keeps passing it to me since the first time i got it and taught it disappeared and didn’t he’s not showing symptoms but i’m sure it’s him. for us women we can use multiple things to get rid of an yeast infection but i’m not sure what’s supposed to get rid of it for a guy. if anyone has gotten their boyfriend/husband treated please i want to know what medication or remedy to use for him.

he does not finish inside me so he’s semen does not throw off my ph balance and he has good hygiene and a clean diet so that’s definitely not it because he doesn’t even drink soda just water 😭
