Can putting soap in vagina makes your vagina itch and burns no std ?

Vagina: yes certainly certain perfumes and types of soaps can cause irritation with burning and itching. Soap tends to dry things out. The vaginal tissue are mucous membranes and are meant to be moist. When they dry out even a little they burn and itch. Use cleansers that have less soap and more moisturizers. It is not necessary to wash inside the vagina or douche. Cleaning the outside is sufficient.
