Sold as boy but not convinced

[beki]

Hi please help
We purchased a male budgie and I’m now not convinced he is male.
He is quite aggressive after being finger trained. Squaks and spits when approached in cage. This is since toys have been introduced. Seems to display female characteristics and I’m was sold him as 9 weeks old but I don’t think he’s 4 mths yet. Had him bout 6 weeks.
I feel like I’m letting the bird down coz I don’t know how to deal with the cage territory thing and want him not to wanna bite and lunge.
The cere is blue pink but nostrils are white.
Please forgive my ignorance I’m a first time bird owner still learning.
