First thing is- don’t worry about it. If it isn’t a big deal to you, don’t act like it! For me, it’s always been much easier when people don’t stress or make a big deal out of my coming out. Let them come out in their own time, and don’t push them any. When it comes time, be clear about your support and make sure they know they can talk to you about it. it’s very important to have someone during the difficult process.
