Thanks. I learned that the immune system does little or nothing to prevent infection of an STD, but determines the severity of disease once infected.
A general question: Unprotected oral sex and protected genital sex are both low risk, but which one is relatively more risky that the other?
I forgot to answer the last question. Condoms for genital sex and unprotected oral sex generally is low risk for all STD and for the reasons above, I doubt your medical condition or drugs make any difference.
My main reaction is that you should be asking these questions of the provider who cares for your lupus and prescribes the immunosuppressive drugs. S/He probably is more expert than I am in judging any changes in your susceptibility to infection.
However, my understanding is that the drugs you are taking don't really have much effect, if any at all, on suscepbility to infection. Their greater effect is in making infections worse in terms of symptoms, potential for complications, etc. For example, you probably are at no more risk than I am of getting, say, a staph infection of your skin; but you probably are at higher risk for rapid progression or for a complication like sepsis (bloodstream infection).
Certainly there are no data to suggest that immunosuppressed people (e.g., persons with advanced HIV infection) are at any greater risk of catching gonorrhea, chlamydia, herpes, or syphilis if exposed. However, syphilis is more resistant to treatment and herpes recurrences are more frequent and more severe in AIDS patients. Similarly, to my knowledge the risk of HIV is no higher in people on immunosuppressive therapy than in other persons.
But as I said above, you should check with your own provider, and rely on his or her responses if they differ from mine.
