Down there problems

So I have this problem, I'm super insecure about my private parts and it's making me not want to have any sex, my vagina is just super wide and long and I honestly hate it, I wish I had that small tight look.. also I have really bad discoloration ! I'm super dark in my tights, vagina, and by my butthollee 🤕i feel like im not good enough due to this... any suggestions on what i can do to improve color and look ? Also my partner always says that he was use to having smaller woman, and vaginas. Like ugh them go with them ! lol leave my ugly thang alone... I just don't need to hear those things..
