Whew, I'm getting seriously cynical, aren't I?
Yeah, the laws are tricky and vary state by state. Some of these “sex offences” don’t seem to merit the level of ostracism that occurs by being lumped in with rapists and pedophiles. I haven’t led a perfect life myself, and there were surely a few times in my teenage years where if I had been caught in the act with my consenting girlfriend who was a couple years younger than me, I would be on one of these lists as well. Now I’m not proud of all of my former escapades, but at the same time my conscience is not worried that I am really an unpunished “sex offender” for my youthful indiscretions.
