I'm 18 and have been questioning my sexuality for maybe six years, thinking that I could be bisexual. I have zero experience at all, but I'm still feeling like taking the step to tell my sister, my closest family member, about my questioning since that's probably the way I'm heading anyway. My orientation has been a hot topic in my family on and off for years now, so I guess I could do this to at least let my sister know what's up. I know that she'll be positive about this and I'm trying to think "Hey, what do I have to lose?", but I'm afraid that my little "secret" could be spread to the rest of my family, and I'm not ready for that yet. Although I will tell her that if I'll end up doing this. I'll also say that things could change in the future since I haven't determined my sexuality yet.
I have a sister, she's really close to me and I tell her everything, even before I tell my parents. So I can understand when you say she's your closest family member. Though I haven't come out to my sister entirely, I think she suspects my orientation. I do know that when I do come out entirely, it'll be to my sister first. So if you think you want to come out to your sister first, I think you should do it. In my opinion secrets between siblings are sacred and they are kept. I'm sure if you trust her to keep it to herself she will. Again, it depends on you. You know your sister more than anybody. My two cents.
