A recent discussion on Threads about morning oral sex has gone viral, sparking debates over why women are often expected to perform it while men rarely reciprocate. Some users questioned whether men are being selfish, prompting a flood of responses from men explaining the practical challenges.
Many men shared their experiences, describing morning moods and partner reactions as risky or stressful. One wrote, “A woman’s morning crankiness can be intense, her leg strength from thigh to calf is no joke—like standing behind a horse.” Others admitted attempts often ended badly or with verbal backlash.
Female users also weighed in, highlighting hygiene concerns. Morning oral may carry higher oral bacteria, and brushing teeth often breaks the “morning intimacy” moment.
Sex educator and YouTuber “1G Laoshi” explained the physiological reasons behind male preference for oral sex. She noted that the penis, especially the glans and frenulum, contains dense sensory receptors. Combined oral warmth, moisture, and pressure trigger nerve signals via the dorsal nerve to the brain, releasing dopamine, oxytocin, and endogenous opioids—creating intense pleasure and feelings of closeness beyond hand stimulation.
She added that the behaviour is tied to attachment and relationship satisfaction. Studies show men’s contentment often correlates with frequency of intimate interactions, providing psychological confirmation of being valued and needed in a partnership.
