What are you hoping to gain by talking to him about it? Are you hoping it will just be one less secret? Are you hoping he'll want to talk about your fantasies? Are you hoping he has fantasies he wants to talk about? Are you hoping he will encourage you to experiment with a woman? What's the goal?
This is what you should think about LadyBree. You stated that you have for a long time not admitted this attraction to women to yourself.
So i think you should first go on the way of self discovery, and by that i don't mean experiment with women, but asking yourself more precisely what you want, what you desire, and what kind of relationship you want.
How would you wish for your Husband to react, how would you want him to help you on your path to find your real sexual identity.
You need to be as clear as possible about what you want.
The next step would be how to admit it not only to yourself but also to others, at first to your Husband. I think it is eventually the right thing to do.
You should not keep a important part of yourself from him, and don't forget that would also mean keeping it from yourself.
So how to admit it to him, and how would you want him to react?
I don't think you can find the best way on here, we don't know you, your husband and your relationship good enough. All i can tell you is take as much information about what you want, what you want for him, what you want him to do, what you want for him, and what you know about him into consideration.
Being shy or not got nothing to do with that if you ask me.
The question i have for you is, is he a fearful guy, do you think he would worry about losing you, that you can go out and he has no problem with you checking out other people, even if he assumes those are men, is to me a sign that he is not the extremely jealous or fearful type.
Is he insecure? Do you think he would feel questioned in his masculinity and sexual ability? Is he controlling? All those things should tell you more about how he will react than his shyness if you ask me, and help you to find an appropriate way to discuss all this.
Finally i can only tell you how i think i would feel, what does a young guy like me who has no desire to get married know tho.
But if i would be married, i would care very much for that person and would want her to be truly and freely herself including sexually.
I might feel jealous here and there, but i think i would support her as it would not affect any of the reasons that would be reason for me to get married.
So i would appreciate a coming out.
