After comprehensive research, visiting In-World Stores checking for the correct links I will call it a day.
I am excited to see that I brought some more listings to life, as there are:
List of Male AO Designers
List of Male Hair Designers
List of Tattoo Designers
Following the links you will find a good source to get the best out of your body, to create it exactly the way you want, being exactly the man you want to be. Have fun and enjoy.
