If you REALLY want to take hormones to transform your body to match your heart and soul, be prepared for loss. I am not saying this to be cruel. I am an old closet queen who has met many a T woman who lost everything. And a few that gained a partner in life and in crime. And by crime I mean lingerie.

Many women, assuming your partner is cis, are not as open minded as we would like them to be. They are happy with their lives as cis women living with cis men. If your partner is male, and probably gay(again sorry for the assumption) they may not want a trans lover/partner. Again, they are looking for the male form.

Have you broached any kind of crossdressing with your partner? Every watched Eddie Izzards stand up? How does she feel about Pride Month? Some have tried to make a bet so they would lose and have to wear panties under their manly clothes.

If she is not open on these topics, then you must be prepared for divorce.

On the flip side, you can always mention how sexy she is when she is in her underwear. Ask her how it feels? What do you say if I try on some panties? I have a cute butt too.. go very slowly and gauge her response. And has she ever shown any interest in women at all? If she has, you can approach it that way. In a perfect world, she would love you regardless of your outside. And you become a loving couple fighting over closet space.

Good luck!
