Some facts about the penis I still haven´t seen here.
- ever wondered why a penis is arrow shaped with the tip thicker than the stem? This is the ideal form to flush out liquid from a tube. Like cleaning a bottle with a brush. When moving forward, liquid inside the tube is pushed to the side by the arrow shaped tip and gets under the rim. When pulling back, the liquid unter the rim is flushed out. Got what I am talking about? Yes, it is flushig out other men´s sperm. Masterful design by evolution.
- The pressure in a fully erect penis can reach up to 50 bar (atm). A car tire usually has about 2 bar. Go figure...
- Little sideline: Sperm actually have different functions. There are "killer" sperm designed to attack other men´s left over sperm, there are "alpha" sperm designed to penetrate the egg cell. Like an army with different divisions...
In connection with that, there´s sense to two cases that made the headlines lately. One chick in Austria and one in Britain sued guys to have them tested because they got pregnant. In one case, there were 17 (!) guys to be tested, in the other 13. What slYts.... But biologically it makes sense. If you want the best genes for your offspring, have yourself fYcked by as much men as possible in a short period of time and then have their sperm fight it out. Funny but biologically reasonable.
Nature is full of wonder...
