Don't forget for point 3) that you have only had 2-3 shaves with a straight?

I had the same problem exacerbated by very coarse beard hair. I can't remember who stressed it to me but your skin also needs a week or two to get used to the fact the straight takes away more dead skin than a Crap III or a DE so your skin is more irritated until it becomes more used to the effects.

For me I let the coarse hairs affect my shave and I was trying to shift them in the first pass and adding too much pressure, as my skin wasn't used to this treatment it got very upset and let me know all about it!

Si.
