Exposure risks, please help!

[LaneMyer]

I tried to be safe, worried it wasn't

I was initially worried about HIV and HSV exposure, it appears the risks are "lottery winnings" low.   From what I read about Hep however it can last a long time outside of the body.

I picked up a sex worker four weeks ago for a hand job. I had her use Purell first.  She was using left hand.  Things were taking a while so I put some lotion on her left hand.  I then asked her to finger herself with her right hand as an additional turn Then, she decided to switch hands! Before I could stop her the right hand was on my penis.  I'd say she got in a stroke or two as I screamed no; there wasn't more than a second or two after her hand left her underwear and then was on my penis but there certainly would have been trace amounts of vaginal fluid present.. I tried to be careful but there was the unpredictable.  The fluid would not have entered into my urethra but would have been on the meatus part.. I instantly nuked my penis with purell.  I'm guessing I had developed "micro tears" from the dry masturbation prior to the cream and there could have been a pathway to the bloodstream though those.

*Would any of the remaining hand cream left there provide any form of barrier?
*Would the Purell nuke have any chance of killing the virus before it got to the nerves?
*So if she was accute/cronic how bad of a transfer vector would this contact be?
*Chances are she was an IV drug user.  I'd guess she was in her early 20s, so it is possible she would have had immunizations as an infant, but would that have "worn off"?

I have a SIGNIFICANT anxiety disorder and always catastrophize .  Very costly lesson here.  I'm drinking like a fish and mixing in benzos right now;  very bad.  Some information might help with my catastrophization.  I've gone through weeks of severe anxiety about HSV and realized this really wasn't a vector; but am now petrified of Hep.  I know I'm going to have psychosomatic "symtoms" and will avoid asking about those.

When can I accurately test?  I wish I would have known about the injection post possible exposure.  I'm going to get vaccinated if it turns out I didn't catch it.

What do you think? All replies greatly appreciated

Requesting feedback again,

Here's a drastically less verbose description for my question.

I was getting a dry handjob from a sex worker,
she used Purell beforehand
After a while hand cream was applied for lubrication.
The sex worker was rubbing her vagina with her other hand and then placed it onto my penis for a very brief period.

What are B and C risks for that brief contact, assuming she had vaginal fluid and possibly trace amounts of blood on her hand?  I believe B risks higher.

contributing factors
creme was on my penis, would that be providing any barrier towards infection
I instantly applied hand santizer to my penis afterwards, would that help at all?

Please weigh in on my risk..  
THANK YOU so much.
