I had the leep surgery , my partner and me we're unprotected before i got it done? could he infect me again? if we continue.

Yes: I am assuming you had an abnormal pap smear. majority of these are due to hpv. this is very prevalent in the entire population up to 98%. I also has hpv and there is no barrier protection used during intercourse he could reinfect you. he needs to see his primary care or even a urologist to be evaluated. until then he should use o condom or you could even use a female condom.
