Snorting Cocaine after touching vagina

I visited a massage parlour in London and received a hand job from an
English sex worker. She then asked me to make her *** which I did by
rubbing her clitoris.

When I was finshed I snorted a line of cocaine off her *** cheek. I am
now very worried about the possiblity to introducing HIV into my body
via my nose because I rolled up a piece of paper with the hand I used
to pleasure her, placed the rolled up paper in my nose and then snorted
off her bare skin.

I can't figure whether my thinking is irrational or not but I am very
concerned. Please help me by giving me some frank advise. Should I get
tested/am I at risk?

this was very out of character for me, which is probably why it is making me so anxious. thanks for the feedback.

Any other opinions would be welcomed
