I prefer a-la-natural. I have done the brazilian thing for a while, which DH loves but its part the whole sexual attraction thing, it keeps the pheremones there and it's definately a more musky/animal/raw scent during DTD kwim? Not a dirty/unclean scent, but completely natural and a real turn on, same with DH's hair.

As for cleanliness, I shower everyday, sometimes twice during a heavy AF so I don't see how that's an issue for me.
