I can't remember how old I was exactly... 18 or 19? I came out as gay, though later realized I was bi/pan, to my mom with a note because I was pretty sure she would be accepting, but I wasn't about my dad. Neither of them really cared? Like it wasn't a big deal.
The only negative thing I think coming out did was stop getting us invited to Thanksgiving at my super Christian aunt's house. But you know... Fuck 'em. 🤷🏻♂️
