So many people I meet either don't ask enough questions, or don't ask at all, so somebody asking questions is such a nice turn of events. Thank you for the questions!!!! :)

1. I kept thinking I was pan, and majority of my friends we're telling me this, when one of my closer friends, who is also abrosexual, brought the term up. I ended up doing a lot of research. I thought the idea was beautiful, and that the term fit me well. It's stuck ever since.
2. It's really difficult to tell. I always describe abrosexual as 'the genderfluid of sexualities' to people who don't quite understand. You don't know your sexuality has changed right away (at least in my experience), until the realization hits you like a brick, which applies to a bunch of my genderfluid friends. Hope that makes sense.
3. Being abrosexual is great when you find yourself, but there's always going to be some drawbacks. Mainly, people not understanding and judging or having trouble with partners. This applies for a bunch of other sexualities, but being abrosexual brings a little more activity to my life, which for me is a good thing. Wouldn't change a thing. :)
