"They don't fit me!"

"I'm healthy"

It doesn't matter how healthy and fit you are, anyone who has unprotected sex puts themselves at risk of catching an STI and also unintended pregnancy. Most people think "it won't happen to me" but the 790,000 diagnoses of STIs annually across the country tell quite a different story.

What's more, you or your partner may not even realise that you have an STI, as many have no noticeable symptoms (Chlamydia is symptomless in at least 70% of women and 50% of men). So just because you cannot see any obvious symptoms such as sores or warts, doesn't mean that one of you doesn't have an STI.

Chlamydia affects up to one in 10 sexually active young women, so remember you can't always tell by looking at someone if they have an STI. Don't take the risk and always use a condom.
