Sexual exploitation can be hard to recognise because you often believe you're in a good relationship with the person - or people.
The relationship could be with close friends, a boyfriend or girlfriend -and maybe groups of friends from school or the area you live in. It could be a person or a new group of people you've only just got to know. It could be someone you've talked to online.
These older adults are nice to you - they show you a lot of interest and affection in the beginning - they make you feel special. Sometimes they ask groups of young people to come back to their house with older people.
As we grow up, we develop relationships with lots of different people. We all have to learn to enjoy healthy relationships, and that's a great skill to have.
But things can go wrong along the way, and people might try to take advantage of you, forcing you into dangerous situations before you know it.
They offer you drugs and alcohol- a place to chill out or involve you in activities that seem exciting or fun. They may even buy you presents like clothes, a mobile phone, or give you money to buy things.
When they have gained your trust and affection, they may change how they act around you. Their aim is to draw young people like you into swapping or selling sex. They are not really your friends.
That person may start to try to find ways of controlling you, such as making promises they can't keep, threatening you, or even becoming violent if you don't do what they want.
They might also try and seperate you from your friends, family and other people who care for you. When that happens, it's easier for an abuser to put you in dangerous situations or force you to do things you don't want to do with them or other people they know.
They will ask for sexual favours for themselves and/or other people, in return for alcohol, drugs, presents, money; all the things they gave you free a while ago.
Three top tips to keep safe
1. Trust yourself to know when something is wrong. If someone makes you feel unsafe, pressured, trapped or frightened, follow your instincts straight away.
2. Don't trust people you don't know, even if they seem friendly - and make sure you know who you are talking to online. Never give away personal details or agree to meet someone who you have only talked to online.
3. Don't be tricked into doing things that are unsafe, even if they seem like fun. What might look exciting at first could be more harmful than you realise.
Talk to someone you can trust
It's not always easy to talk about this, but it is important that you do.
Sexual exploitation can happen to you, no matter whether you are a boy or a girl, and no matter what your age or background - so you need to be careful who you trust.
