I can't comment on the dating part, but I will tell you to just relax around your kids. You are NO danger to them at all.
You can hug them, tickle them, kiss them, share food with them, even utensils and share drinks. I have two children now grown and gone. But they are both negative. We were just like any family. I did tell my children about my status when I felt they were old enough to understand. They were around 10 I think. I, like you did not want to tell my ex, but one of my kids did that when she was a teenager and mad at me at that moment. (Teenagers...gotta love 'em otherwise you'd kill 'em :)) It was a bit rocky, but we got through it and it sure is easier not hiding it anymore.
Anyway you sound like you have a great attitude. Don't spend too much time looking back on 'how this all happened'. It did and what's important now is just to take care of yourself. You sound like you have a great attitude. Good Luck.
