Daemon shows his genuine care and attention to Rhaenyra several times before the two marry. This doesn't take away from the many destructive and inappropriate parts of their relationship, but the books imply that Daemon does love Rhaenyra.
They have a lot of love for each other and Daemon does still support Rhaenyra despite his temper in this episode. He still bends the knee to Rhaenyra and calls her his queen, and he's the one who delivers the news to her at the end that Lucerys (Elliot Grihault) is dead.
Laena and Laenor end up dying in the same year in the book, giving Daemon and Rhaenyra the opportunity to waste no time and get married themselves. In secret, of course, so King Viserys can't stop them. They go ahead and start having kids of their own, including Prince Aegon the Younger and Prince Viserys.
It is only after this realization that Rhaenyra makes her first move on Daemon, instigating with a kiss after she affirms to him that she is no longer a child.
Yet, it is not until Rhaenyra begins to speak of the prophecies of Aegon the Conquerer, the Song of Ice and Fire and the Prince That Was Promised, that Daemon strikes out and begins to violently choke her, causing his wife to gasp for breath.
Rhaenyra Targaryen (Emma D'Arcy) and Daemon Targaryen (Matt Smith) finally had sex on House of the Dragon. After teasing their deep connection for weeks, making out in a brothel, and flirting their way through King's Landing, uncle and niece at long last did the dirty.
Daemon shows wife Rhaenyra the message; she recognizes that if Luke's claim to the title is questioned, so could the legitimacy of her three sons with Harwin Strong. Daemon puts a hand on Rhaenyra's belly. She is pregnant with their child.
Daemon struggles with impotence. This may also be why he has fathered no children with his wife. When Rhaenyra was aggressive in their encounter, Daemon's loss of control changed his handle on things.
Laena and Laenor end up dying in the same year in the book, giving Daemon and Rhaenyra the opportunity to waste no time and get married themselves. In secret, of course, so King Viserys can't stop them. They go ahead and start having kids of their own, including Prince Aegon the Younger and Prince Viserys.
Viserys refused to marry Daemon to Rhaenyra despite the rumors of their tryst, but that didn't stop Rhaenyra from daring Daemon to take her to Dragonstone and make her his wife while at her wedding to Laenor. Despite wanting to take one another, Daemon and Rhaenyra had to marry separate spouses first.
And, in result, she asked Daemon to marry her—and to do away with her first husband. After Laenor was seemingly murdered by his lover, who was paid off by Daemon, the prince and princess wed in an intimate ceremony attended by their children. (For the record, Laenor is not dead, as he escaped with his lover.)

By the fireplace, Rhaenyra says that this is bigger than their ascension. She mentions the “Song of Ice and Fire” prophecy. Daemon grabs Rhaenyra by the neck, choking her and saying that Viserys wanted desperately to make his reign more significant. He says dreams didn't make them kings, dragons did.
After reigning for a decade, King Baelor I Targaryen dies after fasting for 41 days, but some rumors suggest his uncle and Hand Viserys Targaryen poisoned him. Nonetheless, Rhaenyra and Daemon's youngest son becomes King Viserys II Targaryen, with the crown passing through his line.

According to the accounts of Septon Eustace, prior to her turning sixteen, Rhaenyra lost her virginity to her uncle, Prince Daemon, after he seduced her.
This clears the answer to the question. It was Criston Cole to whom Rhaenyra lost her virginity. While Dameon (literally and figuratively) introduced her to the world of sexual pleasures, it was Criston Cole who was the object of the expression of her desires.
Rhaenyra and Daemon's sons Aegon, Viserys, and Visenya Targaryen.
So, who is the real father of Rhaenyra's children? In the show and in George R.R. Martin's Fire and Blood novel, it is heavily implied that Ser Harwin Strong, a knight and the captain of the City's Watch, is the true father of Jacaerys, Lucerys, and Joffrey.
Daemon married Rhaenyra to restore the glory he once held. Daemon was after Rhaenyra from a very long time, he named her 'Realm's delight'. He trained her to seduce Criston Cole according to mushroom.
House of the Dragon
Eventually Daemon leads Rhaenyra to a brothel, where he takes her to a back room. He explains to Rhaenyra that marriage is a duty, but sex is an important source of human pleasure. From there, the stage is set for some good old fashioned creepy Game of Thrones incest.
