This kid who was in my class and left because he was hated was kicking rocks at me then 15 minutes later he wanted to shake my hand and the other boys were laughing. I think he touched his penis then shock hands with me can I get a disease or a STD from this if it is true?

If a person has a wart on their genitals and they touch the wart, and it was totally clean (no masturbation) and hand shakes someone, could they pass warts? even thought no sexual contact has happen.
Please post your answers.
