This is where I also found acceptance in our early days together. I will say that the feelings of excitement or acceptance would come and go for me, and I hear from other spouses that this is true for them as well. I am happy for you both that she could find a loving place with your female self, but if she doesn't find it next time? Well, have patience.
As to why in the bedroom and not elsewhere? For me, it was the only place that felt safe. What goes on in the bedroom is private after all (except for places like Susans!). No one else sees - which for us, with 4 kids seemed huge to me.
Quoting Rayalisse:
Generally her comment is "that just makes you look girly." (but she says it as if that's a bad thing...)
This. "Girly" as a bad thing. This is the ugly head of inner misogyny and the crux, IMO, of why most SOs cannot find the intimacy needed to maintain a marriage. Inner misogyny is what results from growing up hearing "girl" used as a putdown. It is a place of shame and so is hard to see sometimes. In some ways it is not very different from inner homophobia or inner transphobia - the forces that keep people in the closet to their dentriment.
And yes, I can understand your joy and relishing of her attention as a compliment. My wife also loves compliments and I do love to shower them on her. But please remember that your wife loves them too. My dear wife is ever so generous in her complimenting of me, praising my taste in clothing, my outspokenness, whatever it is about me that she loves, I hear about it! Some wives experience jealousy of their transsexual mates. I suspect this could be alleviated with plenty of loving attention.
Happy to hear of you happiness!
