Hi Dr Betty!
I am 18 years old and worried about the damage I may have done to my vagina. I discovered I could pleasure myself at 3 years old, by rubbing my clitoris against a sofa arm, and now regularly masterbate using the corner of a wooden desk. I am aware that this is really unhealthy as it is such a harsh movement, and I am worried that I have desensitised my clitoris or damaged it. Furthermore, as I tend to rub on one side, one of my labia majora has become much larger and more stretched than the other, giving my vulva a lopsided look (although I know vulva's come in all shapes and sizes I feel like mine is not normal as my masterbation has unnaturally stretched it).
