You could not have HIV from what you describe as that is NO risk activity. The only risks for HIV are having unprotected vaginal or anal penetrating sex or sharing IV injectible drugs. Those are the ONLY risks. Frottage is not a risk. Air inactivates the virus. Your symptoms are not HIV related as you could not have HIV. SCREENING means what it says, a test screens if you have HIV, as in it has a definition of SHOW. Shows you if you have HIV. You don't. You had ZERO risk.
