The shape of the sperm is a component needed in order for the sperm to penetrate the layers surrounding the egg. Each sperm needs a head, tail, and mid-piece.
The sperm structure containing enzymes to break down the egg's protective coating is called the Acrosome.
No. It does not have strong enough 'swimming' capabilities to penetrate clothing, including cotton.

When the sperm penetrate the egg cell fertilization occurs.
An acrsome is an organelle that develops over the anterior half of the sperm's head. Its purpose is to break down the outer layer of the ovum so the sperm can join the egg.
Sperm has enzymes that breakdown the outer coat of the oocyte. It takes many sperm with all their enzymes working together to accomplish this.
Sperm cells fertilize the ovum, they are not fertilized. The primary reason for how the term is used is because most sperm compete to reach and penetrate the egg.

Semen consists of 2 components: the sperm component and a fluid component. Sperm is produced by the testicles. The fluid component is secreted by the prostate gland, bulbourethral (or Cowper's) glands, and seminal vesicles. The fluid component provides nutrition for the sperm as well as neutralizes the acidic environement of the urethra of the penis and the vagina of the female.
If the sperm are not "healthy" or present in enough numbers they will will not have the ability to reach and female egg and then penetrate and fertilize then egg.
Once a sperm penetrates the egg, changes occur on the membrane, effectively making it impenetrable to others. It is possible, however, for 2 sperms to penetrate at the same time, which could mess things up.
