Childlike high schooler not fitting in and wants to return to homeschool.

I have 5 kids. The older three are in public school and the younger two are homeschooled. All of the kids started out as homeschoolers. My 11th grader and 7th grader both started public school in 6th grade and love it. They are involved in sports, clubs, and have made a lot of friends. They are ahead academically.My 9th grader is struggling more with fitting in. It's his first year old public school. He didn't want to go to public middle school so we allowed him to continue homeschooling. He's ahead academically but very behind socially. He's never been a social butterfly and he's also a lot more childlike and innocent than most kids his age. He would much rather stay home and play with Legos than attend a school dance. He doesn't have any interest in girls yet and that's fine but leaves him out of the loop with a lot of the guys in his grade. He doesn't play sports and wears more childish clothing. Things like briefs and character tshirts. As you can imagine this makes him a target for teasing (not outright bullying) but he refuses to change. He hasn't even looked up porn yet and thinks the entire process of sex is disgusting. He can't talk about it without covering his ears and asked for us to sign off so he doesn't have to take sex ed as a part of his health class. He watches cartoons, doesn't have social media (by choice), and overall seems much younger than he is. People think my 7th grader is older.I don't know what to do. He wants to go back to homeschooling but I never intended homeschool in high school. There are co-ops and things available but I would prefer for him to stick it out. What can I do to help him fit in better while staying true to himself? When do I pull him out of school? via /r/Parenting https://ift.tt/2PWNNLf
