If you want a serious relationship, se_x on the first date is crucial, according to new research.
More than a third of men found love after sleeping with their partner on the first date .
And 56% of women have had se_x with their partner after the first date, the study highlights.
It has led to a proper relationship for 36 per cent of women and 34 per cent of men, IllicitEncounters says.
But women are slightly more wary than men of partners who want to jump into bed straightaway.
One in six women (17%) said they would think less of someone if they had se_x on the first night, compared to 11% of men.
More than 2,000 people were surveyed for the research.
Of those, 64% of women and 62% of men had wanted to have se_x with someone on the first date but had held back because it was too soon.
And far more women (40%) have regretted jumping straight into bed than men (27%).
llicitEncounters spokeswoman Jessica Leoni said: “The clear message is that if you want to have se_x on a first date, do it.
“We have all grown up about se_x and only prudes are going to think any less of you if you jump into bed on the first night.
“Online dating has speeded up the way we date and this has resulted in couples initiating se_x on first dates far more quickly.
