“What do you think about keeping things PG-rated for a while? We’re both just figuring stuff out. The last thing I’d want to do is hurt you.” Or whatever spin you want to put on the idea that there’s no rush, and plenty of amazing sensations to experience and explore, long before things go further than kissing. Hang out in that PG range as long as possible. And if you can’t talk with your partner about that then you probably shouldn’t be having sex anyway.
Start “home economics” school with them. Laundry, cleaning, cooking, how to change a diaper, comfort a baby, soothe a toddler, what's involved in caring for pets, budgeting for food, keeping track of maintenance schedules for humans, pets, cars and machines. Engage with guests, be a good host, etc. Know when and how to tell someone to GTFO of the house (racist or misogynistic speech, etc.) Every kid needs to learn the art and science of home management. Look for and point out examples in books and movies of good home science skills.

College: you’re gonna do great! You’re also probably gonna want to quit at some point during your first year. Totally normal. If you decide college isn’t for you or now isn’t the right time, okay. But give it a year if you can. You’ll thank yourself later.

They can shower themselves if you install a hand-held shower head and install a suction cup wall-mount shower head holder lower on the shower wall. It’s easy to do and very cheap. They love it!
To paraphrase Ted Lasso, it’s the people who think they’ve got it all figured out who delight in judging people and events. It’s better to be open minded, ask questions. Be curious, not judgmental.
Be discerning about your sources of information. Some red flags: Too good to be true. Get rich quick. Chosen race. Any race or group blamed for societal problems. Fear of change. Threats of real or metaphysical harm (I.e. $@!#%) or bribes with reward.
Discuss the concept that “It’s not always about you.” Some days need to be about supporting someone else in their joy - or sorrow. Your needs take a backseat.
There is nothing “basic” about basic human dignity.
Never treat a person as though they are put on this earth for your amusement.
Everyone deserves to be treated with dignity because we’re all human beings.
No matter their age, looks, status, even past wrongdoing, everyone deserves to be treated with dignity.
