I want to thank all of you ladies for your kind and sensitive advice, and for the stories about your life experience. I joined this forum to find out what was going on in my head, and everything I've read here has helped me so much that I feel like an entirely new person.
The best piece of advice, by far, is "Don't hide it from your spouse."
When I woke up this morning, I made up my mind, that this was going to be the day. I've been on pins and needles all day, hyperventilating, pacing back and forth, having second thoughts, chickening out, then screwing up my courage. Finally, this afternoon I called her into the bedroom and told her the score. She was a bit shocked -- I'm very masculine -- but after I explained the whole thing to her, passing along a lot of the information I picked up here, she said "Well, OK."
I feel like the weight of the world is off my shoulders. I don't have to worry about getting outed to her, I don't have to worry about secret stashes, I don't have to pretend I'm someone I'm not.
Thank you, all of you.
I love you all.
