Hello, and I hope I can help you today. It is true that vaginal atrophy can cause your vagina to shrink, become less elastic and for your vulva and vagina to get very dry. Your clitoris can even atrophy, meaning it can shrink too, leading to decreased sensation. It certainly is safe to attempt sexual activity again with vaginal atrophy. However, vaginal atrophy can be treated, but it takes a while for the skin changes to be reversed and you should practice with lots of foreplay over time before attempting intercourse to make sure your vagina has loosened enough to accommodate the penis. Topical estrogen cream (available by prescription) applied to the vulva and inside the vagina daily for a few weeks should make the skin more stretchy and increase lubrication, then you can use the cream less often. Use plain unscented mineral oil as a lubricant (it is better in post-menopausal women if you re not using condoms). If you (or your partner) are able to insert two fingers comfortably in the vagina (which can take even a month or more), you should be able to have intercourse relatively comfortably. If your vagina is very narrow, gradually dilating the opening over time should make the vagina stretch enough to make intercourse possible. There are other hormone replacement products that also help with vaginal dryness, and a new medication marketed in the U.S. as Osphena which may show some benefit but I prefer topical products as they are not significantly absorbed by the body. I hope I was able to adequately answer your question today and that my advice was helpful. Best wishes, Dr. Brown
