I can't speak for the sensitivity issue as I'm a Williams and Palmolive guy,
but over on one of the wetshave forums, Badger & Blade, one of the members
(Scotto) offers 10 ML samples of various creams....6 for $19 or so including
shipping.

Perhaps someone here can let you know what might be some good
choices for you, or drop Scotto a note and ask him.

He also has colone samplers available as well, and combines the two into a
"gentleman's starter set"- 6 creams of your choice, plus 6 scents, all for $30

Right now he has the following creams:
