This is the term for telling people that you are Lesbian Gay Bisexual or Trans.
How, when, why and who you come out to will vary for all of us. Some people are only 'out' to thier friends, some people are 'out' to everyone. We do not judge you on how 'out' you are, if you are not even sure yourself then 'coming out' can be scary, you can talk to us about 'coming out'
'Coming out' is unlikely to be something you will do once, and how people react may be very different every time, you may 'come out' to your friends then want to 'come out' to your parents or workmates.
