I had an encounter 2 weeks ago with another 18 year old girl (I am 18 also). It was unprotected but was only for a couple of minutes (was after a hard drinking sesh and struggled to stay erect). I know that there is an exposure here but with her only being 18, I doubt she would have HIV. Do you think I should get tested or wait until symptoms occur? I have been getting a sore throat / itchy skin.
