“Outie” vagina

So I’ve always been uncomfortable with the way my vagina looks and I even considered getting surgery (labiaplasty) to fix it. I decided not to go through with it because I’m trying to learn to love my body. My boyfriend wants to take a step further in our relationship and I keep saying no because I don’t want him to be grossed out when he sees it. Idk how to get over it and I need some advice. I’m 18 by the way and I’ve been dating him for a little over a month. Ive also never really done anything with a guy besides him.
