Does hiv die the moment it dries?i mean if a fluid is hiv positive, if it dries, does hiv die just after it dries?or it takes more time after drying ?

It's dead: You're not going to get infected from it. From your profile, i gather that you think you may have infected yourself while enjoying your body with unwashed hands. You're almost a grown man and you owe it to yourself to distinguish the real dangers of being sexual from the imaginary dangers. If you shook hands or touched somebody and then yourself, you can't get hiv. Have you talked with dad?
