Sexual harrassment at school?

When I was in highschool sexual harrassment was very common. My sister and my bestfriend were always being touched by boys without their consent. Boys would grab and pinch their butts, pull their hair, shove their hands up their shirts and grab their breasts. I was never harrased at school (for the most part) but out side school when I would go skating a creepy guy grabbed me and pulled me into his lap and rubbed his penis on me so I elbowed him in fear. Another creepy guy grabbed my breast. What is wrong with the boys in my area they seem to have such little respect for women?
