Who should I come out to first?
Many people start by coming out to the people who are most likely to be accepting of their trans identity. This way, they’ll have a support network around them if they choose to come out to people who may respond negatively.
In order to gauge whether someone will be accepting, some people “test the waters” by bringing up a trans issue or trans person in the media, in order to see how that person responds.
You may also want to choose who you disclose to based, in part, on whether you trust their ability to maintain your confidentiality.
