Harmful Digital Communications Act 2015, s 4 (see definition “intimate visual recording”)
It is illegal (depending on the exact situation) for someone to send, share or threaten to send “intimate images” of you without your consent.
“Intimate images” are photos or videos of someone nude or semi-nude. Even if you took the image yourself and sent to another person, it is a breach of your privacy if that person shares the image when you expected them to keep it private.
If this has happened, contact Youth Law or a Community Law Centre to help you assess your situation.
