I have just finished the series Best Summer Ever and I am absolutely starving for more. I like the highschool type of coming of age with a ton of sex and a well throughout character. I have already read the Ordinary life series by Blue Dragon and anything similar to that series also helps.

Well, my "Country Bot, City Girl" has a bunch of that. It starts when the main character is 16, and his girlfriend is 14.

And there is a lot of sex, but no incest. And the characters do age as time passes, this actually takes place over more than a decade in time, from 1981 to the mid 1990's.
Have you found the stories by Don Lockwood yet? Just about every one would qualify, particularly his Naked in School contributions. However, first and foremost is his novel, Dance of a Lifetime.

CWatson also contributed to the Naked in School idea as well as other growing-up stories. https://storiesonline.net/a/CWatson
You will find the GYounger Stupid Boy series at https://storiesonline.net/library/author.php?name=g-younger&sf=alpha&so=asc&p=2
And for something entirely different .... Growing up is not all fun [but there were a lot of games] look at the Jay Cantrell series about Brock Miller. https://storiesonline.net/series/1278/brock-miller
How about Double Time, or Living Next Door to Heaven by aroslav?
Maybe also Banner Year by Shrink42, or the incomplete Pete: A Young Man's Story, or 17th Birthday by SmokinDriver.
I'm really not sure that my own story qualifies as 'a ton of sex' (though the amount is creeping up, perhaps), but that's in the eye of the beholder. I'm prone to having one reader say 'there's no sex!' and another saying 'it's all sex!' so I'm not really sure what any particular reader will think.
That said, coming of age (in an unusual way) certainly fits, and it's pretty much all character-driven, so:

Many of Aroslav's (already recommended by someone else) certainly fit.
Also, Michael Loucks' A Well Lived Life fits everything on your list: coming of age, high school (and college, and adult life), quite a lot of sex, and well thought out characters.
