im a new sugar glider mom for a few months now is it okay to have two neutered males with one female? please let me know as soon as possible

I don't think the sex matters if they are neutered, the biggest issue will be will they WANT to be together.
proper scent training before neutral territory introductions will be important for a successful introduction.

If your gliders sees the other as an invader (rather then a friendly addition) they will fight.
