The survey, by the Public Health Agency of Sweden, found in comparison that only 51 per cent of young men were happy with their sex lives, with 17 per cent describing themselves as "rather" or "very" unhappy.
This compared to 11 per cent of young women, who described themselves as unsatisfied.
But not all the findings in the report, Sexuality and Health among Young People in Sweden, painted such a rosy picture of young women's sex lives.
The report also found that as many as four per cent of men between 16 and 29 said they would be annoyed if their partner suggested using a condom, compared to just one per cent of girls.
At the same time, girls were twice as likely to report having had unwanted sex.
"Girls and boys do not take on an equal amount of responsibility for contraceptives and testing for sexually transmitted infections," the survey noted, arguing that this was part of a pattern of gender inequality affecting young Swedes' sex lives.
"The preconditions for good sexual and reproductive health and rights among young people are unequal since groups among girls and young non-binary gender persons experience abusive treatment, discrimination and sex against their will and sexual abuse," it concluded.
The report found that 54 per cent of female respondents reported having had sex against their will or suffering sexual abuse at some point in their lives, compared to 27 percent of males.
It also found that a higher proportion of girls (29 per cent) girls than boys (15 per cent) reported having experienced some kind of discrimination or abusive treatment.
"We can see that girls are much more affected by sex against their will than boys are and that is an inequality that we have to deal with," the report's author, Anna-chuchu Schindele, told Radio Sweden.
