The lubricant is a substance which is introduced between two moving or sliding surfaces to improve efficiency, reduce wear and friction between them, dissolve or remove foreign particles and distribute heat generated.
During sexual arousal, a woman’s vagina typically becomes lubricated, making it wetter and ready for sex. Many women find that lubrication makes sex more comfortable or enjoyable because it reduces friction and irritation.
However, sometimes women experience vaginal dryness. The vagina does not lubricate enough, leading to pain or discomfort. This can happen when estrogen levels drop during menopause. Vaginal dryness can also occur when a woman is breastfeeding, undergoing chemotherapy, or when she has been treated for breast cancer.
