Lots of bumps and zits on my chin

[markevens]

I'm still pretty new to the straight razor scene, and had my 5th shave yesterday. Things have been progressing well (read here) and I got a decent shave.

However, this morning my chin had lots of red bumps and 4-5 white heads. I'll get the occasional white head and zit, but never 4-5 at once, and certainly not accompanied by a dozen red bumps.

Shaving the chin has always been a pain, its improving with each shave, but I might be going a little heavy handed. I noticed that with the harder areas I tend to put pressure on my skin, where as the easy areas I keep the feather touch.

Here is the stuff I've been using:
Dovo Prima, sharpened by Lynn, shaved with 4 times. Stropped before and after each shave.
Mitchell's Wool Fat soap
Dominica Bay Rum aftershave
