Why would you mow the grass right after it rains?
Edit: You are comparing an unrelated "pleasant" smell (I'm neutral on cut grass, but I get your point) with something that people already know how it's supposed to smell.
With fragrances, neither males or females naturally smell like flowers. A lot of women seem to enjoy smelling/smelling like flowers.
As a man I also enjoy smelling flowers (but I'm not big on artificial fragrances in general) so I don't feel like a grass smelling cake is a good comparison.
I appreciate it. ๐ซ
