Hello, I wanted to ask what condom size I need. My penis circumference is 13.5 cm. Google says 64 mm, but I don't know if that's correct. And how can I make the purchase as unpleasant as possible?
Hey, can you help me with the question of which of the two hypotheses is correct and how this can be determined from the given experiment with the green algae?
It works for millennia. In each generation, the penis becomes, for example, on average 0.2mm larger or smaller.
But the (rigid) penis does not become more bumpy. Why would it be bigger? Too big is just a disadvantage as too small. Only the sleepy penis changes. Blood penis, or meat penis. The size of the testicles does not change. Not by the temperature. In one case, the bag hangs further down, in the other case, it is denser on the body.
No.
The Allenian rule refers to evolution over many generations, but certainly not to an individual.
The egg temperature is regulated by the body. It is always about 2 degrees below body temperature. The sperms need this.
