Hello,
I'm from Hong Kong, I recently had one night stand with a girl of unknown HIV status (4/10/2018). Before the penetration, I rubbed my penis (without condom) against her vagina for 1-2 minutes then had sex with her using condom. Today (18/10/2018) I developed a fever about 38 degree with intermittent pain on my urethra. But I do not have any discharge or pain in urination. I was diagnosed with Non-gonococcal urethritis 2 months ago and was treated with antibiotic and the recent test showed I was negative for NGU and HIV. I would like to know what the risk of contacting HIV from the activity above is.
Many thanks
