First off I would say you got married before you ever had a chance to discover you sexual identity which is not only toxic to you but to your wife and the future of your marriage.

I would ask your wife how she feels about you exploring your sexuality but if she isn't on board then you may need to leave her behind.

I've heard the old maxim about being married but what good is a false marriage? I'm not saying that you don't love her but that doesn't mean that you should remain married to her no matter what.

Most importantly be open with her and yourself communicate your needs and hopefully she will understand and support you.
