I have what looks like a wart on my penis. can i have genital warts if i've not had sex before or any sexual encounter ?

Unlikely: If you have not had vaginal, anal or oral sex, you are unlikely to have warts on your penis. It is not feasible to say what the lesion may be without examining you. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
