Vaginal Atrophy can cause a lot of distress for individuals
Disclaimer: While I do work in healthcare, have a graduate degree in public health and have worked in the women's center at my undergraduate school, I have not gone to medical school. If you have serious questions/concerns regarding your own vaginal health, please go to your local OB/GYN for their medical advice. This document is being used solely for educational purposes and as a "starting point". This article is not meant to be used to self-diagnosis purposes in any shape or form.
Vaginal atrophy is known as the "thinning" of vaginal tissues. This can be caused by a variety of things such as (but not limited to): menopause, chemotherapy, radiation, giving birth to a child, breastfeeding, traditional cigarette smoking, ovary removal via surgery, douching, and perimenopause. When discussing cancer, unless it is a type of reproductive cancer (clitoral, vulvar, vaginal), rarely is vaginal atrophy mentioned as a side effect. Vaginal atrophy is a potential side effect from chemotherapy and radiation that can last for a very long time post these medical procedures as well (some people have said it's lasted over a year post the end of treatment for chemotherapy and radiation).
Vaginal atrophy normally causes the following signs and symptoms for a person: feeling like one has an "itchy vagina", painful (or impossible) insertion of hygiene products (tampons or diva cups for example), burning sensation while urinating, bleeding and/or discomfort with vaginal intercourse, and decreased lubrication when it comes to masturbation and/or vaginal intercourse.
There are a variety of lubricants one can use to help this issue (masturbation or intercourse options). Please discuss with your doctor to see what they suggest (given your own life circumstances, what you're allergic to, etc.). Some might even suggest the "mini pill"(a type of birth control that is hormonal) to try to help vaginal atrophy. Please do not feel shame or embarrassment when discussing your vaginal health. Trust me, you aren't the first person to experience vaginal atrophy!
Numbing cream is not recommended. Why? Pain means something is wrong and no type of masturbation or intercourse is inherently supposed to hurt.
