A sex survey of 3,000 people has revealed the 'ins and outs' of sex in the UK by asking couples intimate questions about their love-making.
It was said that most couples try out just three positions during the average sex session - but end up with the standard 'man on top'.
Two thirds of couples also admitted the 'doggy style' method of love making is their second favourite, followed by 'woman on top' with 57 percent.
The study also revealed the average sex sessions lasts a speedy 24 minutes… and worryingly, yes, that includes foreplay.
TOP 10 SEX POSITIONS:
1. Missionary - man on top
2. Doggy Style - man goes behind
3. Woman on top
4. Spoons - man lies behind
5. Lap love - she sits on his lap
6. Legs on shoulders - he kneels, she puts her legs on his shoulders
7. The Wrap-around - she puts her legs round him
8. The Organ-grinder - he goes on top, she puts her legs above his shoulders
9. Scissors - legs intertwined
10. Reverse cowgirl - she sits on top and faces away
Half of those polled reckon they were far more lustful and passionate in the early days and sex definitely lasted longer.
And more than half said they'd like to have sex more often - and have it somewhere other than the bedroom, which is the usual place for 89 per cent to make love.
A spokesperson for UKDating.com, which conducted the poll, said: "This research seems to suggest that Brits are relatively inhibited in the bedroom, and prefer to stick with positions they are comfortable in, and know work.
"Incredibly one in 10 couples polled admitted they only ever have sex in one position - which makes for a very boring and unsatisfying love life.
"But the research also shows 78 per cent of couples don't initiate sex until late at night, by which point they are probably exhausted by the day's events and looking forward to a good night's sleep."
