You may notice aging in your face first but other areas of your body are also affected – including your vagina and external genitalia. As oestrogen levels drop with age the internal vaginal walls can lose strength and thickness while the external ‘lips’ can thin and lose their plump, healthy pink look. But it’s not just aging that can take its toll. The stress of childbirth can also affect sensation in the region as the vaginal walls undergo some significant pressure – not to mention the hormonal changes.
