It is unfortunate that you contracted HPV without having sexual intercourse. There are about 70+ strains of HPVs and all of them cause different types of symptoms including warts. However, it is unlikely to get infected with HPV and genital warts by swimming in an infected pool. Some HPV infections are transmitted by direct skin contact also. Do you remember such a situation when you had some skin to skin contact with any infected person? Anyway, your warts will become dormant and HPV will become inactive in about 2 years as your body immune system take over the viral infection. Hope my answer helps. Take care.
