I had sex with a sex worker a week back. I used the condom before starting the intercourse but after the sex I could see the small red dots on the penis head (foreskin) and there is itchiness on the foreskin. Is it because the blow job she gave before the intercourse because I wasn’t wearing a condom when she performed the oral. I thought it's normal and will be ok in 3-4 days but it's been a week and it's still there. Although red dots have reduced and lightened but itchiness still persists. Is it a serious disease or just an infection? And how can it be cured ?
