93% of young people say their partner has threatened to post explicit or intimate videos online when they fight.
The shocking findings come from Women's Aid which is launching its #TooIntoYou Valentines Day awareness campaign.
The data comes from 20,000 responses to an online quiz that was launched last November.
83% said their partner has hit them, 72% said their partner demands to look through their phones and know their passwords, while 62% reported feeling forced or pressured into unwanted sexual activity.
Mary Hayes who leads the #TooIntoYou campaign, says many 'red flags' have become normalised as part of young peoples' relationships
"We have seen some really shocking trends coming through in the #TooIntoYou Relationship Quiz.
"A common unhealthy behaviour we hear about from young people is when their partner demands to look through their phone and social media to see who they’ve been talking to.
"This is really worrying because it is an indication that their partner is trying to control who they talk to and doesn’t respect their privacy".
Women’s Aid has launched a pop-up Valentine’s Shop experience on Dublin's Henry Street to help highlight relationship red flags.
The experience is designed to start a conversation about healthy and unhealthy relationships and shine a light on unhealthy behaviours.
