Sir/mam my case is not of sexual dysfunction. My query is very strange actually today I met my old friend (a highly unreliable) I have a handshake with him and had a coffee with him. So after the meeting when I was driving back I have discovered some very minute scratches on my wrist (very small and 2 in number). These scratches are only after this met and we had handshake many times. Maybe because of his nails. I have read somewhere that aids community people spread hiv deliberately. So I am very worried now as I cannot understand the reason for this 2 little scratches. I am very worried now so please help me as I can not share this issue with anyone. please help me sir and also tell me the worse outcome. I can also send you the picture of those two little scratches on the back of the fingers.
