How can I feel more secure about my private parts?

Do you know some tips or something that can help me overcome my insecurities about my private area(vagina)? I really do hate it. I've always felt the labia was too long and it sticks out and it's just ugly, although I know it's entirely normal, I just can't show my boyfriend. We have sex in the dark and if it's light I hold his face in line with mine so he can't look down. He had insecurities with his privates too, saying it was small, but eventually he began to trust me when I said I didn't care what it looked like. He can quite openly just walk around the house naked and stuff in front of me now, so now I just feel like a letdown. He assures me he loves it and he doesn't think my parts are horrible. I have never shown any guy; when I went for a swab today with my nurse, I was fine with her looking at what I hate so much. She said it was healthy and clean and normal, but yet still I think it's too ugly and disgusting to show my boyfriend. I REALLY want to, though; it's ruining our sex life, I just don't know how to overcome my fear :(
