Hi, I am not married and never have been so, so in that aspect of marriage and sexuality I do not have much experience to add input or advice to you.
I have been struggling with my sexuality for decades, and to date I have determined that for me, I believe that in the intimate relationships with that of the same sex were confusing for me and my MI and still struggle in the terms of if I am either Gay or Bisexual.
In the last almost 7 years I have not had sexual relations with either sex and though in some ways I long to be close to a Man and be held or spend time with, I desire not to have intimate relations, I had one time a gay lover who later married and once he then married, I decided that my own personal policy on this would be for me to not or end all intimate or sexual relations with him, as I see it when he married he chose one sexual partner, took the wedding vows and I do not much like to think of myself as being an adultress in the area.
I have had to realize that for me, I feel I will never marry a woman as I am not 100% certain that I could be strong enough in the flesh to not fall in love with a Gay man and thus Hurting her, so for me, I find that the answer is in my situation to have good and loving friends.
I hope that it all works out between you and your husband, and believe that indeed honesty is the key to any relationship.
Take cAre,
