I recently moved to a third world country permanently and have no access to the exclusive fancy brands. On top of that my third world salary wont suffice for international purchases.

I shave with a dovo disposable straight razor. I had a strop and a fancy black acrylic straight razor. I got the strop technique down and everything, but I simply like the disposable blades better.
I got the sickest brush too, silver tip badger hair, so the tools are of no issue.

Ive thought of myself as a mcguyver and used a sensitive skin shave cream and lotion for after shave, since we technically shave our skin off leaving it vulnerable. But i feel this isnt good enough. Ive heard of just water like all commando, ive done that before but i dont feel its healthy. Ive been straight razor shaving for some years now.

What im asking is, how do i mcguyver this?

Pre shave
Shaving cream
Aftr shave

Olive oil? Random shaving cream? vodka as after shave?

Thanks in advance!
