There are so many myths developed around sex, it can be difficult to know what is true and what isn't. While some are obviously not the case, others can be a bit more difficult to work out.

Knowing what is the case and what isn't when it comes to sex can save you a lot of trouble - and even a bit of pain!

One thing that people seem to be unsure about is whether a lot of sex really can give you a urinary tract infection (UTI).

No one wants to think that something as pleasurable as sex can come with a downside, but sadly for all you ladies out there, having a lot of sex in a short space of time can result in this uncomfortable side effect.

No matter what the reason for a sex-filled weekend, if you have a lot more intercourse than usual, you could end up with an infection. Unlike a sexually transmitted infection (STI), a UTI can be caused by protected or unprotected sex.

You might think that this is an uncommon occurrence, therefore limiting the chances of you getting an infection after a couple of frisky days, but it is actually very common. In fact, this type of UTI happens so much, it is actually known as 'honeymoon cystitis' among experts.

The reason a lot of sex can lead to a UTI is that the tube that goes into the bladder - the urethra - is next to the vagina. This means that vaginal bacteria can end up in the urethra following a lot of sex. The bacteria then travels to the bladder, resulting in a painful infection.

While you might think that the infection is caused by bacteria transferred from your partner, it is most likely the case that it is your own bacteria that causes the issue. This means that it doesn't matter if your partner is new or if you've been together for a while.

So exactly how can you lessen your risk of a UTI without missing out on fun in the bedroom?

Lubrication is a key factor. Using a lubricating gel if you are planning on having a lot of sex can help to reduce irritation - which can be uncomfortable anyway - and tearing, both of which can increase the chances of an infection.

Even something as simple as peeing before and after sex can help, as it will flush out any bacteria that may have found its way into your urethra.

You might also want to keep cranberry extract to hand, especially if you're prone to UTIs, as this stops the bacteria from staying in the bladder.

If you do get a UTI, you can find cystitis relief at pharmacies or your doctor can prescribe antibiotics.
