Thank you for posting your question. Is it possible to forward a photograph?
Thank you. These appear to be Molluscum Contagiosum, rather than warts.
The good news is that, unlike herpes, once gone, they stay gone and, unlike genital warts, there are no cancer causing strains. They most likely did arise from sexual contact, but they can be contracted at gyms, swimming pools, wrestling mats. They are caused by a virus. They are contagious as the name implies. They are usually treated by freezing or the application of a blistering agent called Cantheridin. You can also try using Poxiderm, Zyderm or Molluscum Rx. These are liquids that can be found in drug stores or purchased on line. They usually resolve in 3 months or so on their own, but can persist longer, sometimes much longer, if untreated.
I would be happy to answer further questions.
They have an incubation period of about 2 weeks, so some which are very tiny cannot even be seen yet.
No totally harmless.
Aside from the above, they can be curetted by the physician but I would not recommend this on the scrotum. There is also a trick in which one puts duct tape on each bump and replaces it each day, but again I would not recommend that on the scrotum. So, I would stick to what I already mentioned.
I am not sure of the three over the counter agents ( Poxiderm, Zyderm, or Molluscum Rx) works the best. I wrote a paper on the ingredient in Poxiderm and it worked in that study.
