Hi. I am a male who gave another male a handjob. I spit on my hand and then gave a handjob. It was a random guy that I do not know. He never ejaculated and after I stopped I went to the bathroom and washed my hands before I touched myself. So do I need to be tested for STD’s? What is the chance I contracted an std such as hiv from this??? Please help. I am slightly paranoid.
