Penis. No, it has no affect on it.
No, the penis is not shortened by circumcision.
Penis length has nothing to do with getting a girl pregnant. Ejaculation is what occurs, releasing semen/sperm into the female's vagina. These sperm then fertilize the egg and the female becomes pregnant. A 2 inch penis can get a girl pregnant, as well as a 12" penis as long as he ejaculates.
Yes, penis does affect radiation.
Penis length has nothing to do with weight.
No, it doesn't. The length of the penis is determined by the erectile chambers within the penis (the corpus cavernosum), not by the length of the penile skin.

If there was sperm on the penis then there is a 2% chance of pregnancy.
There is a great variability in the length.
Yes...well, that is, it can. If it is too thick it could hurt for the woman or if it is way too thick it may not even fit. Female stimulation is all about the clit, so rubbing on that with your penis or fingers or tongue is what gets the girl off, not the thickness or length of your penis.
The depth of the penetration or the length of the penis used has absolutely no bearing on whether a woman gets pregnant or not. All that matters is that viable semen was ejaculated into her at the right time in her cycle.
There is no definite length for a penis, they come in all shapes and sizes.
