While its not easy for a male to get yeast infection from their female partner however it does happen if the case is severe and if the male partner has weak immune system. For instance, if you engage in oral sex then he may get oral thrush or throat pain. He can also develop jock itch which simply sucks.
If you been having sex with your partner then I suggest you get on a yeast infection diet and make sure to take probiotics (try probacto probiotics they are made for yeast infection) + cfort10. I would suggest you give your bf/husband probiotics as well.
Give it at least 2-3 months before you see significant changes.
Another thing to know which I forgot to mention is that if you leave it untreated then it can have severe impact on your sex life because sex will be painful and you will experience discharge plus things can get complicated and you will develop UTI which can then turn things to smelly down there.
So get probacto probiotics and cfort10 and start with a good diet.
