Let me also say welcome to the site, I hope you gain as much from the guys here, as I have.
I think you did a wonderful job of explaining the whole situation in your post above.
Hit the print icon at the top of your computer screen. Include Rogers reply, then make a plan for an evening at home. Be sure to allow plenty of time, and turn off your cell phone and unplug the land line. Then share the post with your wife. Let her read it, and be prepared for all the questions she is bound to ask.
Just because your prepared for the questions, doesn't mean you have to have all the answers. Explain to her that you are just starting to try and figure this stuff out. You can also say that you're not ready to share some of the details. Explain to her that you want to be honest and open, but you are just not comfortable with everything yet.
Also try to explain that your recovery will be a long process and you will need and include her. Ask her to be the first person in your support network, then tell her you are going to do your best to build on this network. A good T, (therapist) and maybe this site can be a good addition to your circle of support.
I hope this will help, it is just my opinion, but I know the feeling of "Telling is Healing". As you say, the weight on your shoulders has begun to lift, and releasing the rest of the "load" will feel just as good.
Good luck, and let us know how things turn out.
Your new friend,
P.S. Just a link to a post I made called ... "Telling is Healing". http://www.malesurvivor.org/board/ubbthreads.php?ubb=showflat&Number=197654&page=0&fpart=1
