The biggest risk associated with exchanging personal information via Whatsapp sexting is the potential for someone to exploit it. This could be a malicious individual who obtains your contact details and starts harassing you, or it could be someone looking to engage in online fraud. If you’re sexting with someone you don’t know very well, there is always the risk that they will take screenshots of your conversations and share them without your consent. All this can be extremely damaging to your privacy and reputation.
