Develop and maintain an environment of trust between your boys and yourself. I'm sure you already have it, but make sure to keep it. Always keep a line of communication open with them. Make it so they WANT to talk to you about everything. I think back to my childhood and am eternally grateful for my mom. Because she came into my life when I was 6 years old and was in my eyes, 'taking away my dad', she had to work up my trust. By the time I was a senior in HS, I told her everything.
For instance, when I finally disbelieved in Santa, I tried to rub that knowledge into my younger siblings' faces. She took me to the back room and told me that if I wanted to help with the 'Santa duties' that I need to keep quiet about it to my sisters. Funny how that worked. And my 'Santa duties'? Writing the tags out. Since I'm an artist, I was able to make it pretty cool looking.. ANND it wasn't obviously my mom's handwriting.. lol
Anyway, I can understand where you are coming from, Jules. I had the best mom in the world because she did those things with me. Hopefully it helps you some.
