I think an appreciation for fragrance grows with time. My mother, from whom I inherited my nose (aside: my father has very poor taste in fragrance and is best described as a snobby scent bigot who claims many things are like bug spray), has easily 80+ fragrances of an eclectic taste. There are things I didn't like ten years ago that I now love, likewise, there are scents that have lost their luster to me, but I still appreciate the craft that went into them.
So when you ask what a normal man would need, I wonder at which age? Normal is only appropriate in context of age, society, etc. It's a horrible word, and best left to statisticians!
In my opinion, I would recommend a safe but respectable fragrance for work (i.e. something appropriate for the job you do and your co-workers), a fragrance for the evening, and a fragrance for special occasions that is by its very nature, a special fragrance.
When I wake up and consider what fragrance I will wear for the day, the first thing I consider is what I plan to do that day and who I plan to meet. I truly believe that one should tailor what they wear for what they plan on doing.
Many people here do that without thinking: "The weather is warm and humid, I can't wear this one because it'll be too cloying" or "it's flu season and John at the office is sick, maybe I should wear something close to the skin and mild".
Fragrance is situational and quite dependent on the circumstance. I don't really believe 100% in the concept of a normal life, let alone a fragrance that is good for every occasion.
Fragrance is another arrow in the quiver of a well-equipped gentleman and is the icing on the cake for breaking this detestable thing called normalcy.
I wouldn't say that any fragrance enthusiast is 'sick' at all; rather, I'd say they get 'it'. Smelling good (and bad) things is one of the pleasures of life. Our discourse here on the subtleties and varieties of scent is, in my honest opinion, a noble pursuit. It's very much a study in personality.
