Thats great you’re able to express yourself more around her. I think that after the initial shock most SO’s see that its just clothes and something we are compelled to do and the world isn’t going to end. There are limits and as long as those are respected things should continue to progress.
The acceptance with my SO has developed slowly over the past few years and now I wear leggings, fem tops, and a bra with forms around her and she doesn’t care. She has even encouraged me to let my hair grow long and to polish my nails too. Sometimes we even talk womens fashion and makeup. I try not to push her about any of it and just let her accept and discuss or not at her own pace. We have come a long way.
