"Real" is in the 24th century likely to mean something like nonaugemented. I would average 24th century men expect to have the testosterone level and thus sex drive that they want to have.

Human thoughts used to switch on genes

From a 24th century perspective 21st century people might have an innocence worth writing about because they are so optimized.
Come to think of it, the plot of Brave New World has an element of injecting a retro-model man into an advanced futuristic society, and how a woman in that society reacts to him. Huxley didn't write it as a romance novel, however, because Lenina Crowne's conditioning and promiscuity have impaired her ability to bond with men emotionally (a common topic of discussion in Manosphere blogs); she just obsesses over the Savage's physical attributes, and Huxley cuts off the possibility of her development towards emotional maturity by just ending the novel arbitrarily, with a lot of loose ends.
