Hi I'm Derek and I had sex with a sex worker (protected) but it was her condom and I started panicking afterwards thinking she may have tampered with it to try and spread hiv or any other sti, ever since my penis head seems a little green right next to my pee hole it comes and goes and when I'm erect I seem normal but flaccid it seems greenish and scaly and even sometimes white flakes I kno that maybe a uti but bamboozled by the green any advice apart from don't worry would be appreciated thank you :) lol
