Ok... thanks all of you ... thank you very much...
Dahiyasahan please follow their advices and please dont try to google it.
It's not possible to get poked by a needle and not feel it. Because it hurts! Go find a needle and poke yourself right now and you will see what I mean. Obviously you had no risk because you were not poked with anything.
This is not a realistic HIV concern. First, you would ABSOLUTELY have known if a needle had penetrated your foot. Second, a small prick would not be a risk for HIV. It would require that a needle, with a syringe, plunge into your foot sufficiently to hit a vein, and then the plunger would need to be pushed down. This would hurt - A LOT - and would leave you in no doubt that you had been injured.
Forget about this event and anything like it. Do not ever have unprotected anal or vaginal sex with someone who's HIV status you don't know, and do not share intravenous drug needles, and you will NEVER have to worry about HIV.
I even didn’t wash my food after this ...
