As a registered sex offender, he would most likely forever be denied employment or the ability to live in an apartment. If he was able to get probation for his "offense," he would still have to register as a lifetime sex offender--same problems. (This is precisely the reason a 17-year-old Atlanta boy chose to do a ten-year sentence rather than plead guilty to an offense consisting of consensual oral sex with a 15-year-old. He was released after serving two years.)
But consent is not all of the issue. It is the world we live in today. We have the Internet where our young people live. They are able to be in constant contact not only with their friends, but with anyone who is also as "Internet active" as they are. Anyone, anytime.
