Any muscle can be pulled. However, it is unlikely that you will ever pull your vaginal muscle. A cold compress can be used to ease the pain.
No muscle cells push, it just depends which muscle is doing the pulling. In a common joint, one muscle is used to pull the body part one way, and a different one is used to pull it back.

In medicine, an antagonist is a substance that interferes with or inhibits the physiological action of another substance. Antagonists are often used to block receptors or inhibit the effects of certain neurotransmitters or drugs in the body. Examples include beta-blockers, which are antagonists of beta-adrenergic receptors.
If I'm not mistaken I believe that for this movement to happen there are two muscles that need to be used- because muscles work in pairs. For this particular movement I am sure that the Agonist muscle (prime mover), the muscle that relaxes, is the Bicep. And the Antagonist, the muscle that contracts, is the Tricep.
A pull up bar is used as a piece of equipment to build the upper body without the use of free-weights. Most people who use a pull up bar are attempting to increase upper body strength and muscle mass. A pull up bar is used to target the arms, chest, and core.
No one character fits the label, antagonist. But, the antagonist can be something in the physical environment or in the society. The system of Sameness under which the community lives is the antagonist when this more expansive definition of the word is used.
Muscles never "push"; they can only "pull".The only power that muscles have is to contract or relax. When they contract, they pull. Most bones have two or more sets of muscles, and each muscle pulls in one direction; in sets, the muscles can work together or oppose each other, which account for all the actions that an animal or person can perform.
extensorThe triceps brachii is an extensor. It is the large muscle on the back of the arm and is primarily the muscle used for extension of the elbow joint or straightening of the arm. The triceps is also an antagonist of the biceps and the brachialis muscles.ExtensorsTriceps is not a flexor. It is extensor of the elbow joint.

The term means to act against and it is often used when talking about muscle actions. When one muscle or groups of muscles contracts, the opposite acing muscles must relax. These are called antagonists of each other. When the Biceps Brachii flexes the forearm, the Triceps Brachii must relax.
