Not really! You can be fully turned on and not get enough lubrication.
Normally when a woman is aroused she produces vaginal lubrication, but sometimes her body doesn’t connect with her libido. It’s much the same as erection problems: there’s probably a medical explanation (side-effects of medication, diabetes, hormone imbalance if you’re breastfeeding, pregnant or going through the menopause) or because of anxiety, depression, even worries.
It’s just a missing link in the chain, a glitch on your way to sexual fulfilment, so don’t take it to mean that your sexual desire is fake, has disappeared, or was never there in the first place!
