~Sexual content is defined as an words that describes something sexual or images
You cannot trust that everyone is who they say they are. There are many sexual predators who claim to be someone younger then their actual age to get teens to send them pictures.
Sending something inappropiate will never make someone like you more. It is also illegal to send pictures when underage and recieve them from someone who is underage
If someone asks you for explicit images you can always block or remove that person from your social media. You can also talk to a trusted adult about it.
