Congratulations on consistent (I trust) condom use for vaginal (and anal) exposures with CSWs. As you might imagine, there are no scientific data on which to accurately judge risk in this situation. But as a general rule, condom protection is considered reliable as long as the head of the penis and urethra, and the inside of the foreskin in uncircumcised men, are covered. A certain amount of sliding of the penis inside the condom probably is very common -- which, along with direct skin contact above the condom, explains the lesser protection of condoms against skin-to-skin STD transmission (e.g. herpes, syphilis, HPV) than for secretion-transmitted infections (gonorrhea, chlamydia, HIV, etc). In other words, you can assume the base of your penis always is exposed to some extent during condom-protected sex; maybe somewhat more this time, but that's all.

For those reasons, I see no HIV risk here, only for the skin to skin infections, and that risk is always low for any single exposure. Also, from a statistical standpoint, it is unlikely your partner had HIV; in the US, on average fewer than 1% of female sex workers, and probably under 1 in 1,000, have HIV. Syphilis is similarly infrequent, currently a dominant problem (in the US) among gay men. HPV and herpes probably are the main risks, but no higher in this exposure than any other condom protected vaginal sex.

As for unprotected oral sex, that carries clear risks -- relatively low, but still some risk -- for gonorrhea, nongonococcal urethritis (NGU), and herpes due to HSV1, and syphilis if your partner was infected. However, absence of typical symptoms by 13 days (urethral discharge, with or without painful urination; penile blisters/sores) at 13 days is strong evidence you didn't acquire gonorrhea, herpes, or NGU. HIV is rarely if ever transmitted oral to penis, so that's not really an issue. Cunnilingus is nearly zero risk for all STDs.

I hope this has been helpful. Let me know if anything isn't clear. Best wishes and stay safe--  HHH, MD
