Labiaplasty

I’m 18 years old and i have a surgery set for two weeks from now. I have always been uncomfortable with my labia minora, not only because size but also because of the pain and discomfort it’s brought me. i always thought it was normal to have pain doing certain things (wearing jeans, underwear, exercise, sitting with my legs crossed) and i found out a couple years ago that’s not how it’s supposed to be. and now it hurts during sex. i’m really worried that i won’t be able to feel anything after and itll effect my nerves down there? has anyone had it and what were the effects?? is it worth it or should i just leave it the way it is? also i’m sorry i don’t know what other group to post this question in:/
