I have become interested in musks lately too. I also like Kiehl's (oil formulation not EDT) and MKK over Malle's MR.
Recently, I asked the same question on the Female Board. You might want to search it out.
In answer to my question, Kama was highly recommended as an animalic musk.
Also, Madame X was recommended for the same reason and I was told that it would smell nice on a man's skin too.
I think I'll be ordering Kama soon.
Let's see if we have any other opinioins.
