Oral sex performed on a woman

I'm a man who recently performed oral sex on a female,  just for 15 seconds.  She was not menstruating and oral sex was performed like some licks on clitoral hood. I'm afraid of having contracted hiv. How long should I wait to take the test and have 100% sure?

You don't have to waste any time waiting to take an HIV test because you did not put yourself at risk for HIV infection. What you should do is forget about this and move on with your life.

Oral sex is not a risk of HIV transmission--end of story.
