Hi new to HU cash

My current strategy for playing AKs (100BB) in position is to 4 bet jam over a 3bet. Is this too loose? I nearly always seem to run into AA or KK
Admittedly I only have a small sample size but I am curious as to what other strategy's people have. I flat AKo.

OOP I am currently 3bet calling AKs and AKo

Cheers
