Soooo dry and itchy, HELP!

I’m only 17 and recently I’ve been feeling vaginal dryness which is causing some horrible itching (no it’s not a yeast infection). I’m scared to try lubricants from the drugstore because I don’t want them to be too strong or mess up my pH, any other remedies?? Also, what could be causing this?? Please help, it’s so uncomfortable 😩

Update: all I needed was some organic extra virgin cold pressed coconut oil, worked like magic :)
