I don't know how to get the condoms 

If you've completed Bernice's route by the time Lucifer declares you the Messiah, Sylos will be fully available to buy condoms. The other way to get condoms is to break into the school lockers, some of which have a small chance of dropping condoms.

Thanks bro that was helpful
