Looking advice for "coming out"

Hello, I'm Assasel, one of my host's tulpas. The reason I'm introducing myself is because this is my first time writing here and I felt it was required.

I'll keep it simple. Lately, all four of us in the system have been discussing the possibility of telling someone about our existence (or coming out, however you want to call it) to one of the host's close friends, mainly, because some of us want to be seen by someone else beside him. The thing is we've heard some tragic stories related to sharing one’s plurality with others, so I believe it could be useful if any of you out there could share your experience and give us some advice when dealing with this kind of situation, if you have the experience, of course.
