I gave oral sex to a female sex worker...am I at a high risk ?

[RSTHR9]

I had a few drinks and went to a hotel with two beautiful women, I had sex with both of them, not at the same time, always used condom during penetration. I did perform oral sex them, and they did as well with me, this was previous to penetration, my genitals did not come into contact with their genitals without protection. Am I at any significant risk?

However, oral sex exposes you to other STDs. Check the STD forum to get more information.

You had no risk of HIV and are so safe that you don't need to test.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.  
Only adult risks are unprotected penetrating vaginal or anal sex or sharing needles that you inject with but you didn't do that so you had no risk. This sentence is all you need to know to protect yourself against HIV.
Even with blood, lactation, cuts, rashes, burns, etc the air does not allow inactivated virus to infect from oral activities. The above HIV science is 40 years old and very well established so nothing you can add will make your situation a risk.
No one got HIV from oral activities in 40 years of HIV history, so likely no one will in the next 40 years of your life either.
The condom only has to protect the head, so you can move on from HIV fears.
