During and after radiation treatments I used Aquaphor regularly. I don’t need it anymore but it did help soothe that area as well as baths with Aveeno soaking powder with oatmeal. Even after one year I still do not wear underwear, it’s just too annoying. I have a simple bidet that my husband installed on the toilet for cool water relief. This also helps keep things clean since soap tends to dry and irritate this area when I take a shower.
