I work in the perfume industry and I can tell you that no, most perfumes are still either masculine or feminine though there are a few unisex, the best of them being CK1, which is a stunning smell based heavily on amber.
The reason why some people over-saturate themselves with perfume is that some perfumes, musks and heavy florals for example, are fatiguing to the nose so after a while the wearer gets to think the perfume is drying off and goes and applies more. This is the worst thing you can do because it overwhelms everybody within range and it interferes with the "sillage" or wake of the perfume, which is the progressive drying down of the more volatile topnotes then middle then backnotes, which are the musky and woody notes.
Over-zealous bureaucrats in Brussels have decimated the perfume industry by outlawing many of the more interesting raw materials meaning the the old classics no longer smell the same as they did years ago. Even soap perfumes like Imperial Leather have been wrecked and are now a sad shadow of their former selves.
