Science does not support the modern expectations we place on s*x, libido, or s*xuality.
Human s*xual desire evolved as a biological signal of health, energy availability, and reproductive fitness — not as a productivity metric or a performance standard.
Research shows that healthy libido reflects optimal hormonal balance, not frequency of s*xual activity.
Higher testosterone in men is linked with stronger s*xual desire (Travison et al., 2017; PMID: 28324103).
In women, natural rises in estradiol increase desire around ovulation, demonstrating that libido follows hormonal rhythms rather than fixed expectations (Roney & Simmons, 2013; PMID: 23206487).
Stress is one of the strongest inhibitors of arousal; elevated cortisol directly suppresses the neurobiological pathways needed for s*xual response (Hamilton & Meston, 2011; PMID: 20955832).
And s*xual activity itself is one of the most energy-intensive human behaviors, activating cardiovascular, metabolic, and neurological systems simultaneously because reproduction required significant energetic investment (Brody & Krüger, 2006; PMID: 16490016).
The truth is simple:
S*xuality is biologically variable.
Libido reflects hormonal balance and stress, not worth or performance.
S*x is energy-intensive because it evolved as the mechanism of reproduction, not entertainment.
Your fluctuations are human.
The expectations were manufactured.
