Do guys judge your vagina? Teen help

Ok so I’ve read a lot that guys usually don’t and all that but a lot of those responses are men in their 20’s and over that have fully matured and are more accepting of women. I’m 15 and having sex (protected ofc) and a guy asked if u would want to get eaten out. the thing is I would be more than happy to try but I am very self conscious as I have a petite body build with small breast. my vagina also has big ‘saggy’ labia minoras and dark coloured as well. I need advice on this and take in account that this is a teenage boy my age and their mindset is slightly different than a fully matured male.

Xx thank you
