My question is today we were having some junk food in foil and the foil we threw away on that a dog eat the remain and his saliva was on it. Then my friend picked up the same foil and crushed that foil and threw in dust bin but maybe his hands had some saliva of dog with it. Then after playing and all my friend drank water from a bottle and I drink from the same bottle maybe his hands had saliva of dog (very very little amount) that transferred in my hands through bottle and after 3 hours of playing and travelling. I reached my home and then I changed clothes and went washroom I urinated and washed my penis with water and then I washed my handa. Now my question is that is there any saliva particle of that dog remained in my hands and then went on my penis when I washed it. Or am I just thinking very much?
