Hi I Have A Doubt About HIV. Couple Of Days

Hi I have a doubt about HIV. Couple of days ago I touched another man penis. He was showing it to me (with no erection) an I touched it on the penis body (not glance, he was uncut). As he didn't have an erection, I guess he didn't have even precum (I remember I didnt saw any liquid). The point is that I'm afraid about beeing in risk about touching his penis. As he touched his penis before I touched it, I feel sacred that he probably had any liquid and I touched it. After that moment I started looking to my hands to see if there was any cut or little hole were I can be infected. I'm getting crazy.
