Wanting to try out a new idea/try out a new OC idea (gender transformation, futa, non-gender conforming, ambigous gender, etc)

So, I've recently had the idea for an OC who is AMAB character who is either cis-male or intersex and due to having a futa/herm as a mom, something rather straight happened to them at the very end of their puberty as an adult. It seemed like despite ending puberty, that wasn't done for them as they suddenly woke up with a huge rack!

Not to mention of having to deal with finishing high school as a senior and/or entering college, home life and friends, now their identity has been turned upside down and they're questioning if they're even male anymore.
