There's no denying that sex is messy. We don't mean the emotions that can get tangled up in a sexual relationship, the act of intercourse itself can be dirty - and not always in a good way.

Sex isn't like the movies. There will likely be no light breeze that gently stirs your curtains, you won't fall into each other's arms and enjoy a montage of perfectly performed positions, and you definitely won't be able to fall straight to sleep holding each other.

A lot of things can go wrong, from awkward head bumps, unmatched rhythms and broken condoms. However, one thing people don't really talk about going wrong is the condom coming off inside you.

Not only can this cause panic, it can also put you at risk of contracting STIs and of pregnancy. But how do you avoid this happening?

One of the simplest ways is to put the condom on correctly. This means giving enough time to ensure the condom is put on right - quickly fumbling to pull on a rubber can mean it's only around 85 per cent effective - so you should ensure it is covering the penis from base to tip.

When the fun is finished, your partner should pull out straight away. If he waits to pull out until his erection has gone, there is a much higher chance of the condom slipping off inside you when he does remove his penis.

If a condom does get stuck, the most important thing is not to panic. Nothing can disappear inside your vagina forever, so simply stay calm and remove it. If you can't reach, your partner may be able to get it.

You should also get tested for STIs, especially if your partner is new or casual, and take an emergency contraceptive if possible. It is a good idea to take a pregnancy test in a few weeks as well, just to be on the safe side.

If a condom gets stuck more than once, then you and your partner need to check that you are doing everything right when it comes to using protection.
