For the last year every time I shave my labia majora (only where the hair grows) starts itching so bad, that I can't help bu scratch it! I scratch so hard and so much that my labia majora looks swollen and wrinkled. It also looks very dry and it bleeds after I scratch it for so long! I also experience sores after scratching! The itch doesn't go away until te hair grows back.but whenever I shave the same thing happens, this has been going on for a year non stop without a break! What could this be?
