Hi I had sex a couple months ago with a sex worker. I wore a condom and afterwards it was in one piece so I know it didn't break and it worked but something has been bugging me. A few weeks before having sex I burst a small white head on the bottom of my scrotum. I was wondering if there could be any possible transfer from that burst white head ( which afterwards was an open sore. Not herpes or any sti btw just acne from clogged pores) I'm worried what if her vaginal fluids went on the sore on te bottom of my balls, mind you it had been burst several weeks before, is this any HIV risk and does this warrant an HIV test
