Hey I had sex about a week ago but a condom was used. Now im experiencing itching on gentital area and its not the vagina though ,the itching is only on one side. I also notiched little tiny bumps that have no color on one side but its not near vagina. It doesnt hurt, there is no bad smell, discharge, or pain while urinating. What can this be, can it be a an STD? thanks for help
