I told all my friends that I was pan, then came to a realization a few days ago at 3am and realized I wasn't interested in men/male aligned nb. Is there a comfortable way to tell them that? I feel like some that are pan would feel I'm abandoning them and those that are lesbian would feel I'm joining them or copying them. I'm just worried they'll get the wrong idea. I'm also a demigirl, and I'm not sure how to come out as that. Any protips??
best bet is to kinda explain the way you did here and just come out to them again as bi/ply (or lesbian if thats the direction you were heading). chances are, if theyre your friends they wont feel betrayed or copied, and will definately support you in the long-run
as for coming out as a demigirl, if nobody is up to date with nb stuff or whatnot kinda explain it as being part girl, part [ins your other gender here]. if you feel comfortable enough to, bring it up at the same time youre discussing your orientation
hope this helped + best of luck to you!
