If your husband goes down on you, something terrible may happen, especially if he has an免疫抑制 treatment that reduces his ability to fighting fungal infections and specifically warns against oral sex. This medication lower the ability to fight yeast infection and oral sex may be low-risk.
Your doctor advised against oral sex because he fears it could lead to yeast or candida infections in case of profound immuno deficiency and increase his risk of opportunistic infections. Yeast are rarely transmissible by sex and oral sex seems even lower-risk, according to Dr. Hunter Handsfield, a recognized expert in sexually transmitted diseases at the University of Washington.
But, handsfield said that for average person is healthy and well and uses a drug like HUMIRA for their crohn’s disease or methotrexate for their arthritis, he has never heard – nor have his colleagues who deal with immunodeficient patients proscribing either oral sex or any other kind of sex on account of those treatments for yeast infection.
Sharing a partner's microbiome, especially their genitals, has grown increasingly important given the rise of sexually transmitted diseases. But, "sex, per se, isn't the thing that's going to tip the scales very often," handsfield and I agree. Assume that you and your partner are monogamous, that makes the no-oral guidance even less intuitive.
Moreover, yeast infections themselves are often a flare up of someone's own yeast that already exists in their microbiome, so it's not clear why doctors are warning about oral sex, but their guidance is likely based on the potential for cross-contamination to occur.
Overall, if your partner is worried about getting an yeast infection, it may be a good idea to consult with a healthcare provider who specializes in sexual health to get accurate information and guidance. You may also want to use extra caution and avoid situations where there's a higher risk of transmission, such as during oral-anal contact or during sexual relationship with multiple partners.
