Ok, for why guys are perverted, at your age, they're just seeing how girls bodies are attractive, and they love girls. It's a part of their sexuality. It's their way of expressing their fascination with the girls body and a way for them to connect with they're friends since they all see the same people.
Laughing at them- like laughing at their joke- is usually a turn on, but making fun of them is not. And when girls tell dirty jokes, it might be a slight turn off, because guys view girls as this simple, reserved type of person. Someone who doesn't know a lot about sex in general, and I think for some guys the "naive" girl is attractive.
Both can be true or not true, it depends on the guy.
Guys think their funny when they are perverted. Also at teen years they come to the age were there humor is perverted. THey cant help it their imature.
Im a girls so I don't know if it is a turn on to guys but I don't see how it would be a turn on.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
