There has been a sharp rise in the number of cases of common Sexually Transmitted Infections in Ireland.
Over the past 10 years the cases of gonorrhea here have increased fourfold, while the number of cases of chlamydia and syphillis have doubled, according to the European Centre for Disease Control.
Chlamydia is the most commonly reported STI in Ireland, but the report warns the number of cases may be considerably higher because of a lack of symptoms.
Dr Tom Kelly from the Everyman Centre in Dublin, said: "Lack of symptoms does not mean lack of infection and I think people don’t consider unprotected oral sex to be unsafe sex.
"Often when I ask 'Have you had any unprotected sex?' they might say no, and then I'd say 'Does that include oral sex?' and they'd say 'Oh no, I did have unprotected oral sex, but I didn't think that was risky'."
