Is it normal to be nineteen and experience l dryness?

A lot of women go through this at all ages. Im 23 and have dry spells since I was around 17. It will come and go, so dont worry :) Not to give tmi but I went through about 2 years of dryness and now i have more "wetness" than i ever did. so its just your body changing. And once again sorry for tmi
