I had a sex with an escort and before performing sex the escort open the condom and with her fingers touching the inside of the condom before slipping it in. i am really worried that her fingers could have any varginal fluids or blood, and if it did what's the chance of contracting him, especially that i ejaculated into the condom,
many thanks
You do not need to worry about this - you will not pick up HIV infection from what you describe.
The likelihood is that she was HIV negative. In any event, HIV does not transfer via inanimate objects. It is fragile and will be rendered harmless before any possibility of infection.
