Yes, a big welcome to the forum! Do not feel pressured to reveal something about yourself that you are not comfortable with the world knowing. Like you I am pretty private about a lot of details of my poly life and relationships - just my nature.
But please feel free to ask questions or a general nature, if that will help you towards answers that you may be seeking. You may well find that others have had or are having similar experiences to you, and could use to hear the answers as well.
