Reduced lubrication is very common and can be the result of hormonal changes in a woman’s body — during breastfeeding or perimenopause and postmenopause, for instance — or caused by medications such as antihistamines, hormonal forms of birth control, chemotherapy, and medications for ADHD and depression. Also, you may have decreased lubrication if you are dehydrated, or if you’re not fully aroused.
Lubricants can be purchased online or at drugstores, many supermarkets, and sex-toy shops. Whether you’re having vaginal sex with a partner or masturbating on your own, you may want to add lubrication to:
Decrease painful friction in the vagina and/or anus
Enhance sexual arousal by stimulating the flow of blood to the vulva, which encourages your body to create some of its own lube
Lubricate the clitoris; this can create more sexual pleasure and an easier route to orgasm
Change taste during oral sex
Keep vaginal skin soft and help maintain elasticity of vaginal walls
