It is common for most sexually adults to have multiple strains and some may be high risk and low risk. There are no tests for men but if you can get tested and confirm that you do not have the high risk strains, then it is a good chance that he doesn't either. And yes, smoking cigs does increase the chances of getting more genital warts. As does unsafe sex, drinking, stress, less sleep, severe colds, lack of exercise, junk food, no vitamins, etc. You should get tested for HPV regardless of the warts because the pre-cancerous cells can one day lead to cancer (years or decades from now).
