In the fading light, a male moves past a female and catches the whiff of her fragrance.

The scent catches his attention. He turns, sensing she may be the one he has spent his life searching for.

He follows her trail, eager to impress.

What he has detected in these few moments - from this haze of pheromones - is not that the female is his soul mate, a potential life partner, or someone to captivate his mind. But that she is a virgin.
