My Labia Majora Is Irritated.. It's Peeling And It Appears

My labia majora is irritated.. It's peeling and it appears shiny.. Sometimes it itches and I scratch it and the skin tears. There are small patches that are also stripping and is spreading to my inner thighs. My clitoros also itches intensely. When I was having sex, my vagina was dry and intercourse tore my skin when it stretched.
