Dear Dr. Handsfield / Dr. Hook,

I need your expertise to close this chapter. In Germany, I visited a sex worker who strictly enforces condom use (signs in her room).

We had brief, condom-protected oral sex. To relax me, she did a 4-minute digital prostate massage. She later confirmed via WhatsApp that she always uses gloves for this to protect herself from bacteria due to her long fingernails. However, due to severe anxiety, I am unsure if she used gloves, and I failed to check her hands for fresh cuts or wounds. The massage felt uncomfortable, so we stopped, and she briefly finished the protected oral sex.

Did this expose me to any HIV risk, regardless of whether gloves were worn or if she had undetected minor cuts on her fingers? 

Thank you for your invaluable reassurance.
