My husband was showering about 3 days ago. While rushing in the shower, he grabbed some men s shower gel. As soon as he got out, he stated he thinks he burnt his penis. He said that it immediately became cool, but then tingly and a burning sensation. He showed me and it was extremely red. The next day it was still red but it also had a few red bumps and very sensitive. The third day the skin is peeling and somewhat sensitive. Not sure if it matters but he is uncircumcised. What should he do?should he be worried or could this be an allergy to the gel?
