Rhaenyra wasn't one to be very traditional, she was a free dragon who did whatever she liked, whenever she liked. For years she was able to avoid marriage. She just wasn't interested in it at all. In that time, her father had married her best friend, Alicent. They also had a boy together, Aegon. Rhaenyra would remain heir to the crown but she had to make a deal with her father. She would remain heir if she marries and she gets to choose the suitor. Though that wasn't entirely as she had wished, it was better than losing her position as Princess.
Within the next moon, they had organized a grand feast, where suitors from all over Westeros could come and try to win the Princess' hand. Men of all ages came for her hand.

She hoped not to be faced with such disloyalty but she wouldn't be surprised either.
It was their wedding night, they danced and did all the official business that they needed to. In normal circumstances, they would have to consummate infront of everyone to make it official, but by her request he didn't allow any prying eyes. By the end of the night, they retired to their new chambers as husband and wife. She plumped down onto the bed with velvet rushes and feathered pillows, looking up at him with amusing eyes but also carrying that serious demeanor that she usually did.
"I'm not letting you have me tonight, understand? I'm not some thing you breed whenever you like and I also don't want to hear anything of you chasing other skirts, or you'll be sorry every time you come into this room." She wasn't asking, she was telling and warning him at the same time.
