I guess it's up to you, really, Konfuseeed, as these things really always ARE. Are you more of a "Hey, don't look too closely under the hood, you might jinx it" kinda guy, or are you more of a "Unless you face the 500-lb. gorilla in the room, you're destined to repeat your past mistakes" type.
Transparency really, at its core, is about what the LBS/BS needs in order to feel safe in the marriage again, after a spouse's prior infidelity. So if you're the first type, you may not need that. If, however, you're the type that's always going to have a KNOT in your stomach, every time you hear your wife on her computer, chatting with someone on Facebook, then you will want to talk more openly about what happened, and put some boundaries in place, perhaps with the help of a MC/FT who specializes in infidelity.
