When I was a teenager I formed Asew for my video game characters based on a girl I liked, but made it not obviously girly so if anyone I knew saw it they wouldn't immediately think it was a girl's name.

Well it is weird using Asew at the girls night out, apparently it is very confusing (as just like originally intended). I was watching the Chilling Adventures of Sabrina (on Netflix) with close captioning and her boyfriend called her a 'Brina which is an anagram of my given name and I loved it. But since I don't want the confusion like Asew, I think Sabrina is the way to go. Going to give it some more time before a final decision.
