am 23 years old an have been dealing with dry skin under my testicle area. It is very itchy and often will wake me in the night. I have come to the conclusion that this is likely due to sweating, but I don t seem to have a problem over-sweating anywhere else. I have heard that the salt in the sweat may be left behind and can cause skin to become itchy and dry. This is not an STD and I ve tried quite a bit for relief - jock itch treatment, talcum powder, vaseline, even a wide assortment of ultra healing lotions, nothing really works.
