Its been more a month I see this small wart like thing suddenly appears on my penis shaft. It does'nt itching, pain but its dry. I didn't have any sex till now but I do masturbate. I could see my penis shaft becomes dry inside. Help me please. I'm afraid. Can I do sex with this? Does it cause any STD to the girl? if she did oral without condom.
Look at these pictures for better view
