Is it normal for girls to slurp their own love juice? I've never slurped my own semen. It just feels disgusting.
Depends. Each person's taste is different.
Now i'm going to talk based on mine and others experience, please correct me if i'm wrong.
For Female, It usually start out as curiosity about it's smell, then how it taste (since it is more or less a clear liquid, giving the image of "clean"). For most it's just water that need to be cleaned, but if you are too horny, you would sometimes do stupid stuff... If you are wondering, it doesn't really have any taste. The "liquid" it self is tasteless but, every girl give it a unique taste, sometimes a little bit spicy, sometimes a little salty.
Now, for male counterpart, it's still the same. It also depends on each person's taste, but since there is no normal practice (Male don't usually give BJ to each other right?) the reason as to why they did it is different. For male, it tends to be seen as disgusting or repulsive thanks to it's consistency and it's cloudy color. So most don't even have the curiosity that girls experience, but those who do try is mostly (not all) did it: 1. To "recover" used protein; 2. Out of sheer curiosity and horniness; 3. To gain a taste for it; or 4. To brave a whole new world. Now if you are wondering how it taste, it is mostly bitter, like the taste you get drinking alkaline water, but similar to the girls, each person give it a unique taste like salty, sweet, or sometimes sour.
