Hi! Welcome along.

I strop before the shave, to prepare the blade for the shave, & after, for maintenance.
You should strop before each shave. After is personal choice, but a few laps over linen after a wipe over & you know the edge is dry.

Re honing times vary between steels & also stubble. It may be three months, it may be six. You just get it done/do it when you feel the edge is lacking a bit.

You may find you become obsessed, buy razor after razor & rarely need to re hone as you've got too many to use. That happened here once.
