Women are more likely than men to buy their partner risqué gifts to celebrate Valentine's Day.
According to website lastminute.com, women free their imagination and splash out on gifts such as a 'bondage bear' or sexy underwear for their partner, while men fall back on flowers and chocolate.
The online shopping site reports that orders increase fourfold in the week before 14 February, with men more likely to leave gift buying to the last minute.
Paul Shaw, head of leisure at lastminute.com, said: "This year we've noticed a significant increase in the demand for more inspirational presents such as romantic weekends away.
"[Also popular are] adventure activities such as 'zorbing' [running down a hill inside a sphere] or bungee jumping, and more thoughtful gifts like adopting an endangered animal.
"It is obviously getting harder to impress and surprise our partners."
