I can definatly see how people would have self-image problems. Our society is filled with media that advertise these "perfect" people, and we naturally compare ourselves to them. It is hard to be compared to that and everyone wants to look great. Parents are a big influence in self image, a great example is the girl that talked in beginnings. Parents are responsible to be positive influences on their children.
I think probably the biggest issue with sexual assult isn't rape or molestation, but times when girls are not able to say no. For instance, at a party when a girl has had to much to drink and she isn't thinking striaght, thats when most sexual assult crimes happen. It is a terrible evil thing and it needs to be controlled, and one way to do that is stop it if you see it happening. Other people have been sexually assulted at home. I feel extremely bad for these people because they are scarred at such a young age.
Pornography is a slippery slope. The thing about pornography is that it can actually be addicting and many people fall into its temptation. For some, pornography is a release from stress or sexual tension. Porography is bad because it undermines the pupose of sex, and God's original intension.
