It’s amazing how they managed to pack so much misinformation into one short post. First of all, female sex organs don’t just magically “atrophy” after three months of not being sexually active. Second of all, hormone levels and balance are not solely affected by sexual activity.
Various factors influence them, including diet, exercise, and overall health. And third, women’s enjoyment of sex is not solely dependent on the state of their genitalia. So maybe instead of spreading baseless rumors about women’s bodies, they could try actually listening to women and respecting their autonomy and bodily autonomy.
