I came out as poly first and as asexual later, only to my mom. The reason I did them separately is simple: I didn't realize I was asexual at first. I won't come out as anything to any other family member, because I'm not close to them at all.
Heteroromantic asexual female, sex-positive, childfree, relationship anarchist.
Married to G, and in a partially non-romantic, completely non-sexual and long-distance triad with A and L.
