Hi, I realized I left out a few things that might be important, so I'm going to fix it. I'll also provide some bonus information about some characters.

Vocabulary:

Slick: self-lubricant produced by omegas during their heat, it is a sweet smelling fluid. Slick makes it easier for omegas to mate.
*It can get overproduced and leak which leads to emberrassing situations.

Nesting: Pregnant omegas might do it to feel more safe. This activity involves omegas gathering their mate's clothes and using them to build a 'nest'. They tipically use their nest, if they are stressed, feel unsafe or when they've been far away from their alpha for a long time. It calmes them down and makes them feel safe.
*Omegas are very protective of their nests, it's a bad idea to bother an omega when they are nesting. No one can enter an omega's nest without their permission.

Marking: A part of mating. The alpha bites the omga's neck where the scent gland is located. Marking lets others know their selationship status. The alpha's and omega's scent mix together.

Pregnant omega males:
People can act very rude to them. There are people who will use terms generally associated with women to talk about them (call them mothers or wives instead of fathers and husbands), this is seen as degrading. Degrading language also includes people -usually alphas- referring to an omega male as an alpha's bitch. Once they get pregnant omega males are encuraged to stay at home, raise kids and make their alpha happy. Some doctors recommend 'using the natural cure' to heats and make it harder for omegas to get any form of birth control, because doctors think their fertility is a gift that needs to be used.
