Ask your dermatologist or GYN to remove the wart and have it biopsied to confirm it is HPV and to inform you of the strain number. HPV is very common (8 out of 10 sexually active adults have it). The low risk strains that produce warts are not dangerous.
As for how to boost your immune system: Stop smoking cigs if you do, reduce alcohol intake, eat healthy, get more rest, exercise, reduce stress and take vitamins and supplements. Refrain from sex for at least 3-6 months after the wart is gone. Latex condoms provide more protection than unsafe sex. The vitamins I take are: C, E, folic acid, A, etc. The ones that are for immune system boosts. Good luck and stay positive. Depression will lead to more warts.
