I was 13 years old when I started growing breasts, and also had never ending comments that I needed a bra. Similarly, this lead me to trying a bra on my own and discovering that I did fit a bra and liked how it felt to wear one. The problem was feeling like I could not wear one as much as I truly wanted to, with the obvious concerns of discovery and acceptance by others.
I managed to attract a great wife despite a significant physical drawback I felt I had. Eventually she told me that I needed a bra more than she did, and this comment opened the door to full time wearing.
My wife accepts me wearing a bra daily and washes them for me and puts them back in my bra drawer. She has bought some for me while shopping together.
I definitely prefer wearing a bra daily and could not imagine going back to being braless. For me, a button down pattern shirt is a must to feel more stealth in public. I do not understand how some are OK with T shirts, as I would think they advertise the bra straps. Even a very thin shirt seems stealth enough if it is a patterned button down type.
With your wife's positive involvement you are well on the way. Enjoy the positive benefits of wearing a bra daily.
