Hello 24 hours ago my friend and I were studying at a coffee shop with one of our other friends. My friend messes around a lot and decided to try to cut my friend and I with a plastic knife, he succeeded I got a small cut on my hand, my other friend who he tried to cut never got cut, he then cuts himself with the knife and bleeds, and accidentally cuts me again with the same knife. All the cuts were about minutes apart from each other, I do not think he has HIV because he says he is a virgin however I can not be too safe what should I do?
