Pee is stored in the balls
Wee all know that intuitevely, but some might need a rational explination. Ass the song goes this biological fact is pretty easy to explain. Pee is just stored in the balls. Now, the sceptikal of you might say: "That can't be true! Sperm is stored in the balls!". Now here is where you are wrong. Sperm is not stored in the balls, because sperm in fact doesn't exist. It's actually milks.
Milks
Now, what are milks. The name is pretty sugestive if I can say so myself (in Romanian I dub them as "lapți". Yes, I know that means something else, but you are wrong). Basicaly, milk has these little particles, called milks. They contain the protein and such, and are very nurturing. Milks flow through the bloodstream and sometimes build up. This is why dudes have to ejaculate. This is why wet dreams happen. In women, milks are just stored in the breasts. They get condensed and can be stored much more efectively for years if necesarry. That's also why girls and boys go into puberty roughly in the same timeframe.
Now, that's not to say that boy's milks and girl's milks are the same. In fact the diference comes from the condensing that goes on in the breasts. That's also why only girls can breastfeed. Duh. You dirty minded whippersnapper, don't even think about that!
Now your biggest concern probbaly is :"Why don't men have breasts?". This is exactly what I will adress in this paragraph. SO stop asking me so many god damn questions! Leave me alone . Sorry about that. I don't know what happend. Maybe if you stopped being a bithc and listened for a second. What? Ok, so boys don't have breasts because of the y cromosome. See, it's easy.
In conclusion, pee is stored in the balls. Also, women have inverted balls inside the body to store pee. They are called ovaries. Eggs just come from hardened milks.
