I am 20 years male, last month I engaged in a mutual masturbation with my male partner'unknown hiv status'i was touching his penis and I might have touched my penis head, glans with same hand maybe there was precum .i am extremely worried. I had an ear infection after 12 days in left ear with a lymph node (the swelling reduces after 4 weeks) I and my partner didn't ejaculate then or perform any anal, oral. Have I contract hiv? Or any std please reply.
