No worries. Different HPV types cause warts than cancer. Penile cancer is very rare in both circumcised and uncircumcised men.

Yes/no. For one thing, the strains that produce warts are not associated with cancer, but you could have picked up non-wart cancer associated strains the same way Since circumcised men have the whole penis available for monitoring, recognition & treatment before any cancerous change would be easier. There is no 100% prevention with a circ, but it sure helps. Read more...

Hard to say. Condoms can reduce but not prevent the spread of HPV. The wart strains are also not known to trigger cancer.However, the contacts involved in getting one strain can also give you the other strains that are. You can have specific serum studies done to see what strains your body has developed antibodies to. Most are at very low risk. Read more...

Yes. Even though you both have HPV and are sure you have exactly the same strain(s), engaging in any unprotected intercourse or oral sex can increase your viral load (how many virus particles are in your body) and overwhelm your immune system, causing more breakouts of symptoms.
