Shared anal sex toy

Two weeks ago I had protected vaginal sex with a female prostitute, but we also used a vibrator to toy each other's anuses.  I barely inserted it into her anus and used lubricant, so I don't think it would have caused much damage.  After toying with her, we waited maybe a minute, and then she applied more lubricant and started toying my anus.  It never went very deep, maybe 1-2" inside me.  I am concerned that possibly HIV from her anal mucus could have remained on the vibrator and that I may have contracted HIV when she then played with my anus.  Again, there was never deep penetration, but we did not wash between uses.  I'm hoping that the little amount of the virus (if any) would have died off during the minute or so between contact.  

If it matters, I looked at the vibrator before she lubricated it to toy with me, and it was dry and clean looking (no visible feces or blood).

I'm terrified and can't sleep ever.  Any input would be appreciated

your risk is extremely low but not 0

my advise
1-take an HIV test 90 days after your last exposure and you will know the results
2-always wash sex toys before any use
3-always use protection

good luck
