The only way to last several hours in bed is to have sexual games (head, original positions, roleplay, submission, frustration games, etc ...). The french writer Georges Bataille wrote an essay about Erotism.
He analyzes studies that were made in the 50's, and that showed that the richest or the most outcasted people (=mafia criminals to be more precise) had the longest lasting / higher quality sex in the general population (5 hours straight sex on average). There are several explanations to this : they have on average more time and more money, and they like sophisticated games in general, and so in sex.
They are hedonistic for different reasons : the super rich because, well, they can, the criminals because they know their life expectancy is very low, and thus need to make every single moment profitable and intense (and foids are also naturally attracted to this kind of dangerous deviant guys).
Since they are not frustrated irl, these men can play with their own frustration and avoid jerking off during the whole session until the very end, which leverage the effect of the actual ejaculation after several hours of sexual games, "frustration" play, and seeing a female in constant orgasm. Again, the "frustration" here has nothing to do with the frustration of a virgin, it's a well thought calculated "staged" frustration in order to reach nirvana on the final momentum.
They are also generally high IQ or have a good education, making them more willing to give pleasure to their partner : a woman truly reaching orgasm (not pretending, like most foids do today ...) is an excellent catalyst to long lasting male orgasm. Female orgasms also last longer and can be repeated more close in time, which makes a virtuous circle of reciprocal orgasmic nirvana that can last hours.
But this is a really particular way of life. Tbh I highly doubt more than 1% of world population can afford it (5 hours on average means some can last far more ...). Normie sex has nothing to do with this. If one of these hypersexual males had to do normie sex, they would feel like incels and commit suicide asap.
