More than half of women in the Netherlands have been subjected to unwanted sexual contact and nearly a quarter have experienced sexual abuse, according to new research.

A survey by sexual health centre Rutgers found that 22% of women and 6% of men had been forced to take part in sex acts or done so against their will. The proportion who had been touched or kissed without their consent was 53% for women and 19% for men.

The survey of 17,000 Dutch people also found that the majority were happy with their sex lives. Among 25 to 39-year-olds 85% had had sex with a partner in the last six months, as had the majority of people over 70 (51%). Women under 25 and men over 70 were the most likely to report sexual health problems such as pain and erectile dysfunction.

Gay and bisexual men were three times more likely to have had non-consensual sex than heterosexual men, while 25% of gay men and 15% of women said they had been verbally abused because of their sexuality in the last year.

The survey also found that around half of the population saw pornography as a normal aspect of their sex lives. Seven in 10 men and three in 10 women had watched porn in the last six months.
