You wrote this wearing a tuxedo didn’t you ?Technically the name “Perfume” is actually a level oil in the product.
Basically you have cologne which is bottom tier, then eu de toilette and top shelf is perfume.
Perfume or cologne is used to heighten the sense of intrigue. Most wear these products incorrectly to begin with. You shouldn’t walk in a room and people smell the cologne on you. That is obnoxious.
When someone gets close for a handshake or a hug is when the scent should present itself. This helps many things without referencing to trying to attract female or male. It makes for enhanced recollection of said person. This can help close business deals or anything including keeping you on the mind of that girl you just met.
Men have been using scent enhancement since the beginning of time. We just no longer use odd concoctions of bones and odder piss.
