Oompa,
I can't imagine ever going back after i found out the real "truth".
After reading your post, i was darn near overwhelmed with the sacrifice you would be willing to make for your wife, and that i understand completely.
I was at that crossroads last year, and was determined to keep on going and never turn back. Luckily for me, my wife took my hand and started that journey with me. If she hadn't, i may have lingered, but not for long i don't believe. Hard for a man to be something he's not.
In your case, doing it for your wife, and your marriage, i respect that very much, and wish you well.
