Insecure :/

So I have always been insecure about my vagina because it doesn’t look normal and I know that people say all vaginas are different but it’s held me back from doing a lot of things ... I have given my boyfriend head but I won’t let him do anything to me . He has tried fingering me ,eating me out and i always hold back because I am nervous and insecure . I haven’t told him about my insecurities but he always asks me why I don’t let him do anything to me but I just say that I’m scared . I haven’t ever let anyone touch me because of it . Is anyone on here having the same issues ? What do I do ?
