Whatever happened to modesty and personal respect of oneself?

Whatever happened to modesty and personal respect of oneself? "Sexting" really? I have heard of this before, so no it's not new to me, but the part that I find most disturbing is that "in 2009 one in twenty teens (5%)  have used their phones in this way"(Trenholm 304). That was three years ago, and according to internetsafty101.org in 2011 "20% of teens have sent or posted nude or semi-nude photographs or videos of themselves." I guess the term sex sells has taken on a whole new meaning. Despite the fact that it's illegal, it's disgusting. As a society are we so in the "now" moment, that there is no consideration for our future? Is the teenage population so insecure with themselves that they feel the need to send naked pictures of themselves out into the world? Again, according to internetsafty101.org "44% of teens say it is common for sexually suggestive text messages to get shared with people other than the intended recipient". That's almost half of the teenagers surveyed, who inadvertently said they know of or have shared a photo that they knew they should not have.  The statistics are there for everyone to find, but no one  wants to admit to their kid doing it. If we as parents think this is wrong, and morally mortifying, why do today's teens have a common acceptance of it? Is the ease of access to media single handedly changing societies ideas of what is morally ok? I have sooo many questions and fears on this topic. I know the idea of naked pictures seems erotic, but the repercussions 5, 10, 15 years from now will be detrimental to someone's life.
