I've had a wart on the shaft of my penis a month now. not that big, just woundering how to approach the problem. also had warts on my hands 9monthsago?

There's treatment: for genital warts. They are effective but have about a 1 in 3 shot of coming back in short order. Also, if you have warts, then you are contagious for them by unprotected sex EVEN IF IT IS REMOVED AND IT ISN"T VISIBLE

See: Your doctor to have it evaluated and then removed. Find the cause so you get the appropriate treatment

Be careful: Due to the sensitive nature of genital warts(if that what this is) I would encourage you to avoid using over-the-counter wart treatment. This is something better treated by a dermatologist to make sure you don't run into any complications. Also be mindful that warts are contagious, don't risk anyone else's health in the meanwhile. Best of luck.

Depends on cause: If you have had unprotected sex you need to be checked for STD's. See your Doc for testing. Consider seeing a urologist for treatment options. Use protection! A venereal wart (if that is the kind you have) is bad enough but there are worse things out there.
