Never post a pic to social media that you wouldn't want Grandma to see. NEVER send or ask to receive naked pictures.
It's tacky, gross, illegal and not worth it. Even if "everyone does it". It's rude and disrespectful.
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.

Professor Scott Galloway’s advice: Paraphrasing his standard wedding toast:
“1. Express affection and desire. Everyone wants to be wanted. It’s healthy and it is part of what makes your relationship singular.
2. Never let your wife / girlfriend be hungry or cold. Two thirds of the really awful arguments you’ll have it’s because someone is hungry or cold. Carry blankets and protein bars. (You’re welcome.)
3. Don’t keep score. Decide what kind of friend / son / daughter / spouse / employee / human being you want to be, and practice being that. Put the scorecard away.”
Sometimes I think the best way to take care of them is to teach them to take care of others: Littler kids, sick or disabled, those who’ve been left out.
Talk to them about how dangerous it is to buy pills online. Fentanyl is ubiquitous and lethal in small doses. Never never take a pull that wasn’t prescribed or purchased legally.
