Just looking for some advice and/or reassurance, so I'll get right to it. 

I had an encounter with a sex worker where I was given an unprotected handjob, and she also licked my testicles for approx. 30 seconds. During the encounter, I also sucked her nipples and inserted a finger into her vagina.

Am I at risk for any STI? Specifically, I am most concerned about whether the testicle licking I received puts me at risk of HPV or HSV contraction? I know I previously have never had HPV or HSV-2 as I am a virgin (never have had penetrative sex). 

Thanks in advance.

STIs are rarely if ever transmitted by hand-genital contact; or by tongue or saliva contact with intact skin -- scrotum or anywhere else. You are not at risk for HPV, HSV, or any other infection. All is well; you do not need testing for anything.

I hope these comments are helpful. Let me know if anything isn't clear.
