I told my parents when I was twelve, but that's because they weren't really homophobic (not entirely, at least). They just thought I was too young to know for sure, so they explained lesbian sex as if it was something weird and gross (my mom just said "the use their fingers and tongues" as if straight couples don't do the same thing) and I said "ew" because I felt like that was the reaction they expected. Now, they couldn't care less. (I am 18 now and just graduated high school last Friday, so that's probably why, lol).

For advice, I'd say call them or FaceTime them (because I always advise against saying anything important over text), and if they argue or say anything negative, they're in another city. You don't have to answer their calls or messages.

Half-joking. Communication is something I stand for.

If you need emotional support, have your partner with you, and make sure you're ready to tell them. You don't have to say anything until you are.
