I had an oral sex with no ejaculation, should I worry for hiv. I have tested after one month and later at 10 weeks, it came negative. I do not want to test it again. Its very difficult. Does my sexual activity poses risk for hiv? And no symptoms. Also I met with an accident a month ago. And I had an operation in which they have done pre operative medical tests and hbsag/hcv/hiv all came negative.
