About a week ago I noticed two small bumps forming on the shaft of my penis. I went to the urologist yesterday and he seemed to think they were warts and had me schedule another appointment in 10 days. This is extremely distressing for me because as far as I can tell the only cause of genital warts is HPV or some other STD...but I've never had any sexual activity. I don't understand how I could have contracted something like this without even being irresponsible or promiscuous....I'm just wondering if there could be some other explanation. The doctor said he didn't think they are skin tags.
