Hi Again:
It's admirable that you want to avoid potentially hurting your wife.
If you bury this or try to manage it in secrecy, you'll quite likely bring serious pain and discomfort to you both. This isn't to say going slow and understanding yourself might not be helpful - if that's what you are doing. If you are seeking some cloistered way to express and release your discomfort, then you may have begun the all too familiar cycle of denial, abstinence, shame, closeted release and so on.
So many of us here know that path well, and I am not afraid to say I wish I would have stepped off of it sooner, much sooner. But as you've probably heard we come out when we can. Is it time for you? Only you know but in considering this be aware the ladies who have gone before you know the sooner the better.
In the mean time, please stay in regular touch, post here, ask questions, express yourself . . . keeping this matter in conversation is important to your overall well-being. And besides, there's a togetherness in being connected that just feels good and hopefully you find that too. Others will have much to say over time here, and your being a part of the dialog helps everyone in you doing so.
We get where you are and offer our hand as we can to be there for you as friends and sisters.
Take good care,
Rachel
