No, there isn't. It all depends on what kind of sex she had that night / day and whether she squirted or not. My ex gf fucked mostly with a whole gang of black friends at once. Whether she showered afterwards or not her scent varied and I could not tell what was better. When she didn't I could perceive the stench, mix of the men's cum, their sweat, her pussy juices, and anal mucus, rancid and very different from any ladies perfume. Sometimes she reeked like a men's toilet / restroom. And it still was arousing. With my wife it's different. I can tell apart her and his smells on her. Her pussy, pubic area, buttocks and belly smell smell pleasantly of their mixed juices and the smell is more or less permanent now. After changing the bull, it has taken over a week to change her smell. Interesting is though what the bulls say of her smell. They speak of taco-pussy, but I believe they mean the fritanga she cooks almost daily. That must give her pussy juice its distinctive smell which I don't notice because I eat the same food.
