The study found one in five boys "found it hard" to treat same-sex attracted people the same as others, and two in five would not want a same-sex attracted person in their friendship group.

More than 300 14-17 year old boys were surveyed about their attitudes towards same-sex attracted people.

A quarter of boys said terms like "homo" and "dyke" are "not really that bad", and just under a quarter think it's okay to use the phrase "That's so gay" about things they dislike.

More than half of all respondents had seen people bullied for their sexuality first hand, and 40% felt uncomfortable or anxious around same-sex attracted people.
