I looooove Obsession for men. That first smell of it on someone almost makes me feel drunk for a second. It almost transports me somewhere else.
I alternate between a couple fragrances depending on my mood and what I'm doing... Obsession for Women, Chanel Allure, Chanel No. 5, and Coty Wild Musk. All fake-y versions though. Scents change quite a bit on me and the real versions tend to smell too sweet after a couple minutes.
