Keep my razor in the shower as well.
i hate it too sometimes...almost liek I have Two faces to shave
I will admit, sometimes shaving your head can get a bit tedious,especially if you are in a hurry or get up late.
I do my head at night, so it's not so bad if i don't have time in the morning.
But if I do have the time, I make sure it gets done

It's not so bad so long as I get at least one shave a day
I can shave mine in the shower in about 5 minutes if I am in a rush, but I perfer not to rush when shaving, reduces chances of cuts.
I invariably nick myself if I rush.
