Well this is something

It's not a fool proof system but somewhere in evolution it could have helped

also, in todays day, we use deodorant, perfume, and cologne to mask our natural scent

what about in tomorrow's day?

That is a good question indeed! But, what about the day after tomorrow, and then the day after that, and then the days after that to come? Have we ever thought of that? No? Not only the days, what about the weeks, months, years, decades, and centuries to come, Have we thought of that? Are WE prepared for those? The real Question is ARE WE PREPARED FOR THE FUTURE THAT AWAITS US?

Deodorants, keeping us away from 'the one' since forever.
(Pssstt.. insert musk for those earlier in time)
