Any dating founder with advice to ramp up female users?

my app ratio is 9:1 (male/female) lol

It's pretty easy for me to ramp up male users but female I have not found product market fit. I cannot ask the female users because the whole purpose of the app was to be date secretively.

any suggestions are appreciated. or if you want to join me as growth hack, sales co-founder then let me know
