Wht's up bro?! Let me try to help ease your mind.

I recently had intercourse with a prostitute.
I say:
If it was protected, you had NO risk. If it wasn't, you need to test at 3 months, 6 weeks is good indication but 3 months is necessary. The chances of getting it frm one unprotected exposure isn't very likely but you still need to test.

I touched her vagina and felt the fluid coming out. After that I touched her breasts with same hands. I sucked her breasts about 2-3 mins after that.
I say:
No risk bro, no way!
Smile.

Stop worrying and best of luck, if needed.
Always use a Condom, if you did, well done, if you didn't start doing so bro.
