It's your generation raising us ;)
Seriously though, I think the sense of entitlement comes from the parents. My parents have been pretty good about not spoiling me. They expect me to help out, they expect me to pay for a lot of my own stuff, and they don't just buy me whatever I want. However, I realize that I (and all the rest of my generation) am very lucky, considering the circumstances that my parents and grandparents grew up.
All in all, I think that those who think we're pampered are being a little bit judgmental, you should get to know a lot of young people, not base your opinion off a couple you met.
If a woman says, "No" "Stop!", pushes the man off her, is struggling, and doesn't give complete consent, it's rape. If a woman is participating and likes it, just as much as the man, then it is surprise sex. There's a very big difference.
