I have been wearing panties daily since I came out to my wife a little over two years ago. It was actually my wife who suggested that I store my boxers away. (It would take me two more months before I actually did.) I still keep my boxers around for the occasional time that I cannot wear panties due to company, though those times are becoming less and less frequent. As for bras, it is hit or miss. It generally depends on how I feel. I do, however, wear a sport bra whenever I am training or playing sports. I find that wearing a sports bra during athletic activity is just more comfortable than not wearing one.
