Please Can You Advise Whehter In Your Professional Opinion I

Please can you advise whehter in your professional opinion I am at risk of having contracted HIV thanks. I'm hetero and have always enjoyed my g/f's using butt plugs and strap-on toys on me (kinky but fun!). Not having had a g/f for a while I visited a hooker for some strap-on fun which was very enthusiastic and prolonged.......she used a condom on the strap-on but afterwards I came out in a panic when I began to consider how many different guys her strap-on has been used on. I'm now *very* panicky that HIV virus could have been present on parts of strap-on not covered by condom or condom could have had tear and I didn't notice. Am I at risk? Do I need tested? Could live virus have been present on strap-on when she used it on me?
