The Family Federation of Finland Väestöliitto published the results of its family barometer, which was based on the FINSEX survey carried out in 2015. Researchers say that fulfilling relationships are an importance source of happiness and satisfaction for people in Finland.
The study also found that there are close ties between peoples' happiness in romantic relationships and satisfactory sex lives. Often the challenge in people being satisfied with their sex lives lies in the inability to talk about sex with their partners, the group says.
The good news is that about 75 percent of respondents said they were happy in their relationships as well as their sex lives, and considered sex to be an important part of their relationships.
The bad news is that sexual dissatisfaction among people in Finland appears to be rising, according to Väestöliitto researcher Osmo Kontula.
Some 10 percent said they were not happy with their relationships - or their sex lives - and it appears that a lack of sex is often due to a shortfall in other types of physical, but non-sexual, intimacy.
Researcher: Increase worrying
"It's worrying that a third of those who said they were in a relationship said their sex lives were not satisfying." Kontula said. "Since 2007, the number of people claiming to be sexually dissatisfied went up by ten percent. The survey found that increased dissatisfaction with people's sex lives correlated to a decrease in the frequency of sexual intercourse."
The research found that satisfying sex lives are closely linked to having a loving partner, regular sex and mutual feelings of sexual desire. Also couples' abilities to reach orgasm and being able to work through sexual problems were also important factors.
Some 2,150 people in Finland between the ages of 18 to 79 participated in the survey. Eighty-seven percent of the men and 85 percent of the women surveyed said they were in an ongoing romantic relationship.
