i remember being anxious about my first shave with the straight as well. i just shaved on my regular schedule. although, i have an uber-heavy beard. so i do it with two days growth, any more and i take it down with my clippers, i leave enough for the visual gratification. if i shaved everyday, my skin wouldn't approve. i suppose it would, but i'm not going to shave each and every day.thats just me.
if you wait longer, or i guess when you decide to shave anytime, preparation is key. once you get your routine down, it's easy street. for me, personally, it's fun to try new prep things as well. to see what works best. and thats after a billion questions on this forum.
godspeed.
