The outer part of my vagina itches every once and a while. There is no rash or redness, no bumps or bad odor. It usually happens around the time that I am ovulating or going to start my period. Is this normal? I have been with the same partner for the last 8 years, if this helps narrow it down.

Also, sometimes when this happens I itch in my sleep and end up itching too much or too hard resulting in a burning sensation after (happening right now). The burning feeling is closer to the groin/labia majora. Is this because of a fabric burn from itching? And is it safe to use aquaphor on the irritated area?
