In 2008 Relationship Services/Whakawhanaungatanga commissioned UMR Research to conduct an online survey of 1,000 men and women about the sorts of issues couples encounter in sexual relationships. Overall, older women and men were less likely to identify problems in their relationships than younger people. Younger people were more likely to mention problems associated with one partner wanting more sex than the other, and this was more likely to be an issue for women than men. Life problems and difficulties having an orgasm were also more frequently mentioned by younger participants.

The small numbers of men aged 24 and younger in the survey meant that information about them is not included. Those participating in this survey were currently in a sexual relationship or had in the past been in a relationship lasting more than a year.
