Thickness isn't important. The thickness of ejaculate can vary a lot. If you drank a lot that day it can be more fluid, or if you've ejaculated frequently in a couple of days it can be more fluid....so it's definitely not weird to have thicker ejaculate. It doesn't affect your fertility.
Mine is like pancake batter and no kids
No. If a woman is infertile, sperm will have no effect on her. Infertile means she cannot get pregnant.
No
It usually does unless the man is infertile.
Not necessarily. The density of the fluid has nothing to do with the amount of sperm. See a doctor - get him to do a sperm count to easy your mind.
thick
No. Only men produce sperm.
No, it doesn't. Your body produces millions of sperm every day, but only one is necessary to fertilise the egg. But there's no way you can tell if you are fertile or infertile by the color or thickness of your semen. Thick semen probably means that it's been a day or two since you last ejaculated. Thin sperm usually means that it's been an hour or two since you last ejaculated.
Yes. The sperm cells themselves can be abnormally shaped, non-motile or otherwise unable to penetrate the egg cell.

a mature sperm carries 23 chromosomes.
Like a thick liquid.
no, if anything it gets thinner.
