Definitely falls into the Wholesome Smut category - there are consent condoms and communication. I'm also getting that aimless and clueless teenager vibe that makes it feel really authentic. FL appears to be coded as autistic and more strongly than you usually see. It's also told from the ML's POV which is a really nice change. They even have public hair!
I LOVE that she has pubic hair and both her breasts and his d!ck are reasonably sized, not huge porn sized, It's a really nice change.
Oh, and the plot feels realistic. It's that aimless don't know what the heck you're doing teenage vibe. Digging that too.
