Ok here's what happened with me.
Me (at 15): "Mom, I'm uhh, I'm gay."
Mom: "Yeah I know, I figured that out when I found gay porn on the computer. I mean, I know it's not mine."
Me: "So you're not ….mad or anything?"
Mom: "No, just be careful and be safe."
.......
Me (at 16): "Jennifer (my sister), I'm gay."
Jen: "Oh cool, I'm bi. What kind of guys are you into?"
.......
Me (at 17): "Dad, I'm gay"
Dad: "Does your mom know about this?"
Me: "Yeah I told her a couple years ago."
Dad: "I can't believe you told your mother before you told me. I thought you trusted me more than that"
Me: "...Umm, sorry?"
Dad: "Well as long as it makes you happy, just be safe."

Lol, god I love my family's open-minded optimism. Even my friends all thought it was adorable that I was gay when I came out to them. Somehow I get the feeling this isn't the general reaction, but I'm glad my family was supportive. I always feel really bad that I had it so easy when I hear all these horror stories, and I really hope it goes as well for some of you as it did for me.
