Hi. There can be medical exemptions for this. I suffered from severe full body Psoriasis as well as SH issues. It opened me up to the problem with bullying and further sh. I spoke to my pediatrician at the time and they wrote a letter stating that I should be allowed have my free period follow gym so that I could shower after the other people. They made accommodations for me from dressing to shower from 4th grade through high school. It’s worth looking into
