    Oral Sex and HIV
    LouisMay posted:
    A few months ago I had oral sex with a few guys with unknown status. There was never any ejaculation in my mouth. I was concerned about my HIV status so I went to a doctor to get tested. The doctor gave me the INSTI test but told me that the test was only conclusive after 12 weeks. At the time I believed it was about 12 weeks after potential exposure, but after I took the test I went through some old text messages and discovered that it may have been done 10 weeks post exposure.

    My question is should I get retested and what are my chances of contracting HIV with oral sex and no ejaculation.

    georgiagail responded:
    Oral sex, in itself, carries an extremely (and I do mean extremely) low risk of HIV transmission.

    The statistics we use for estimated risk are .5 to 1 per 10,000 exposures with a. a source KNOWN to carry the virus and b. assuming the contact was carried to completion (i.e., ejaculation took place).

    In your instances, neither of the above would be a factor, lowering your risk even further.

    In addition, a screening test done one month post exposure is considered to be 95 percent accurate; that is, 95 percent of newly infected folks would have enough antibodies present to be picked up by current testing methods. By 3 months (12 weeks) this has increased to 99.9 percent. it likely that someone would test negative at 10 weeks and positive at 12? No.

    In other words...and wading through all the stats I've thrown at you...the bottom line is that none of these episodes of oral sex have left you HIV positive.

    I hope this makes sense and brings you some comfort.

    would protected oral sex with no completion be considered a reason to be tested?

    No. Read Gails response above for rates of transmission via oral sex. Even without condom, the risk is virtually non-existent.
