insecure in the bedroom

How can i not be so insecure in bed?? i'm insecure about the way i look down there, i have a darker labia. i feel like i have to hide myself constantly and i'm scared he won't feel attracted to me. he always says he doesn't care and that he thinks i look good and he doesn't want me to cha he anything about myself etc etc... but i don't feel like i look good down there...

they say guys don't care how womens vaginas look but i can't help but feel like he's judging me low key and it's preventing me from wanting to try new positions in bed and have sex during the day time
