I have had the opportunity to be invited into the home of two trans ladies. While I enjoyed visiting, and would visit again if the opportunity presents itself, I don't think we would become "close friends".
I do have two other lady friends, born female...who have been extremely supportive of me. One I have been in public dressed in womens shorts and tank top, but nothing more. The other, I have met and we have had lunch but I was in male mode. But the point is, they both support me as much as I could ever ask them to, and more even. While they live in a location that I cant get to easily, I have been known to go try on clothes and send pics and ask their opinion while I am in the store. The one thing I wish for is to be able to shop with someone who can help me decide what looks good. It wasn't until after I started dressing in female attire myself that I learned why it was so important for women to shop as much as they do...Oh my goodness! Was that a sexist remark? It wasn't intended to be! Please forgive me. But as a man I was always able to go into a store and pick up a pair of jeans and go home with them without ever even trying them on. Not so with womens clothes!
My point in my above ramble is that while the friends who support me the most may not be trans, they are close friends who know me, support me and not afraid to be with me in public when I dress in my girl clothes. Thank you ladies for that!
