BJ amateur

My boyfriend and I are both newbies to giving blowjobs. I'm incredibly self conscious about my lady parts and am nervous about him seeing more than he has already for fear it'll turn him off. There isn't anything wrong with my vagina, I'm just in general self conscious. Any advice on how to beat that? Also tips for giving Blowjobs!! He is very thick around, pretty long, he doesn't man-scape, which doesn't bother me in the slightest, but I need some pointers. :) Thanks ladies.
