I haven’t really came out yet to my parents, tho I have dropped a few hints, but I feel the best way to come out to ur parents would probably be to start off with something like “I love and trust you guys a bunch so I thought I would tell y’all something” and then tell them that ur Panromantic, if they are confused to what that is it would be best to carefully and calmly explain it to them. I wish u luck on coming out!
