There are calls for a course on consent to be taught to young offenders all over Ireland.
Workshops have been taking place at the Hydebank Wood Secure College for young offenders in Belfast, run by White Ribbon NI - a movement to end violence against women.
The course includes talking about the experiences of women who have been subjected to violence, abuse or harassment.
It also examines behaviours often considered as harmless which are allowed it to continue - such as 'banter' and objectification.
The facility houses men aged 18 to 21, but in some cases, inmates can stay until they are 24.
One man taking the course told Josh Crosbie for The Pat Kenny Show it has opened his eyes.
"I have a sister and I have a mother and I wouldn't like anything to happen them," he said.
"Through the course I realised the percentages and how often it happens.
"It opened my eyes a wee bit; could be someone close to you, could be someone living next door.
"It's just awareness, it needs to be talked about, it happens a lot and it's being brushed under the carpet."
He said he too has suffered abuse.
"I've been through experiences myself with a woman; me being abused by a woman mentally," he said.
"I never did go to someone."
'All over Ireland'
He said as a result of this course, he has a better understanding of what to do "and the signs of it."
"That's why this course needs to be done all over Ireland."
Another man in the course said education around consent should have been given earlier.
"This was the first real opportunity in here for me to take on if someone's trying to lead a girl on, or when they're drunk and all and stuff like that," he said.
"I should have heard that when I went into secondary school," he added.
'Influencing other people'
White Ribbon NI CEO Tahnee McCorry hopes the men will take what they learn when they are released.
"There's so much potential for change here, there's so much potential for leadership," she said.
"A lot of the young men were very loud and were natural leaders and I thought, 'They're going to lead something.'
"They may as well lead something really positive, and they can be the ones who influence other people."
Ms McCorry said these men will be the next leaders in their communities.
"I saw how much they were influenced by the leaders in their community, and that might have been positively or negatively," she said.
"They were almost now taking the stand as the leaders.
"That's when I realised if they bring this kind of vigour and this kind of leadership outside, I want them to be talking about the things that we talk about - which is respect, equality and standing up for what you believe in."
'A lot of them were angry'
Ms McCorry said there were some positive differences to teaching in a security environment rather than schools and sports clubs.
"The young men do have time to be able to think about these things properly," she said.
"The differences being that some of these young men have been convicted of something we're talking about, and that's a difficult and challenging conversation to have.
"The only way that we can do it is being as open as possible and encouraging as much accountability as possible, but very much looking towards the future.
"I think a lot of them were angry; 'Why have I never heard this before? I've never seen anything like this before'".
Ms McCorry said she believes these courses should go further.
"This should be rolled out far and wide," she said.
"This style of workshop which we deliver, it has to be conversational.
"You have to leave room to challenge, you cannot leave people with questions leaving the room," she added.
