Planes, trains and automobiles - and just about everywhere else including the shower.
Couples are showing a taste for more adventurous sex, according to a new survey.
Sex in the shower is the most popular location outside of the bedroom - 92% of couples have tried this.
The second most popular location was also in the bathroom - 89% of us have bonked in the bath.
The sofa is third (86% of couples) and in front of the TV is fourth (74%).
The kitchen table is fifth (65%) and the garden is sixth (58%)
In seventh place is romping in a car (57%) before we switch back to the home for sex on the stairs - almost half of couples (47%) have tried this.
More than a third of us (37%) have got fruity in a greenhouse or a garden shed.
Just over a quarter have romped in a garage (26%) while a fifth of us (21%) have done it on top of a washing machine.
Sex on a train was the next favourite - around one in six (15%) of couples have tried this. And one in ten (11%) of couples have joined the Mile High Club by having sex on a plane.
Sex toy retailer Lovehoney asked 1,000 people where they liked getting passionate most outside of the bedroom.
A spokesperson said: "Couples are becoming increasingly adventurous - and that has to be good thing.
"Who wants to have sex in the same place, at the same time and in the same way?
“Sex in the shower was the runaway winner and we find that tends to get even more popular as the weather heats up.
“In the last month searches on the Lovehoney site for ‘Shower Sex’ and ‘Sex in the Shower’ have rocketed by over 700% - suggesting that when the sun comes out, we look at more risque places to have sex including the shower.
"All Lovehoney research shows that couples who are happy in the bedroom have better and more fulfilling relationships. "A key way to keep sex fun and vibrant is by mixing things up.”
Lovehoney sells several products to enhance shower sex including the Sex In The Shower Dual Locking Suction Handle which adds instant leverage to achieve perfect positions in the shower or bath. Lock down the handle on your walls or tiles to enjoy strong grip and even stronger waves of pleasure.
Tracey Cox’s Guide To Sex In Adventurous Places
Just as there are certain sex acts that shouldn't be missed, there are places you should have been naked in. But a word of caution before you consider anything alfresco: not everyone will be as entranced at the sight of your partner's bare bottom as you are.
Not being able to control your surroundings is all part of the thrill - but being arrested for cavorting in public isn't quite the kick most of us are after.
So be sensible. Leave as many clothes on as possible and plan your escape and what to say if you get caught before you attempt it. Don't do it if being caught would be an absolute nightmare or lead to arrest and be aware of the laws in the country you're in. Having sex on a beach in Dubai, for instance, is not a good idea.
Cars are always fun for sex. You could slip into the backseat and enjoy relative privacy but it's far, far, sexier to do it on the car hood. You sit on the bonnet, he stands in front of you.
The urge to be naughty when staying in a hotel is high. If you're abroad and anonymous, you're more likely to do something risky - which is why that night-cap on the balcony to 'finish off the evening' often leads to both of you doing just that - with a bang.
Garden sex is fun, especially on a swing. She wears a long, loose skirt and no knickers, he stands in front, holds the sides of the swing seat firmly, draws her to him and stands still while swinging you to and fro.
Some claim the only time our bodies are truly at peace is when the sun beats down on us because the sun's and body's biorhythms are the same.
In water, we're gloriously weightless. Everything feels light (thin) and buoyant in mood and body (not to mention thin). Finally, tents are a brilliantly low-risk way to have public sex: ask any regular festival goer! There's nothing but a sheet of canvas separating you from the outside world and being able to hear what's going on outside, adds to the excitement.
Hell, even having sex in a tent in your garden is kind of sexy. What would the neighbours think?
