I think they are all (except Lys Mediterranee - never tried it) wearable for men. Especially Une Rose, Carnal Flower and En Passant (after it dries down).
Iris Poudre starts out very much on the feminine side. As it dries it becomes much more unisex.
Cassie, IMO, does just the opposite. It becomes more feminine after the dry down. But, because this is one of the most unique fragrances around, it has to at least be sampled by every scent connoisseur.
Carnal Flower is breathtaking. IMO, its one of the most amazing fragrances ever created. Words fail me.
I am interested in hearing others thoughts about LM as well. I've actually been very curious about this one lately.
