Whenever possible, correct anyone (including him) referring to him as a husband or man, by simply saying "you mean, my Sissy Girl (or boy)".
This is a subtle, but public, acknowledgement of you treating and describing him as a sissy. Not all people will understand when you say such a thing, but he certainly will, and the result will be deliciously and momentarily humiliating.
You should simply and politely correct anyone who says his name or refers to him as "Mr. ….", by simply saying that he should be referred to as "Miss Sissy (name)".
You can do this anytime you are in a public place, such as a restaurant or a check in counter at a hotel, etc. Act surprised if you call or arrive to someplace and he is listed as "Mr. …", then after correcting the woman, turn to him and angrily scold him for not having give his name as "Miss Sissy (name)". Then turn to him directly and publicly remind him that he will be punished later for you having to correct him (that will sginify you are firmly in charge). Then actually punish him in a very feminine way to make sure get's the point and always identifies himself the proper way in the future. Do it every time possible in front of any woman.
Only do this in front of women, as anything else would be a turn off. The only time you should mention it in front of a male, is if you are cuckolding him with the male.
