Hello and thank you for posting your medical question on E health forum.
I understand your current anxiety due to fear of HIV.
From the history described, there is no risk of infection of HIV.
HIV virus does not exist outside the living cells, and is immediately rendered non-infective. Also transmission of HIV via fomites has not been detected or proved to be causative of HIV infection, hence is not a risk.
FOMITE: is any inanimate object or substance capable of carrying infectious organisms. In this case the sextoy, in question is a fomite.
If you still have doubts, you might consider to consult with your doctor who can provide reassurance and also can clear all your doubts that you may have.
