If you have sex with someone who is very different from your usual type, it alters the nature of your sexual network. This alteration can impact on the spread of infections, particularly when a network with higher rates of infection overlaps with a network where infection is less common. Take, for example, gonorrhea in Australia, which is far more common among younger than older gay men. If someone from a network of mainly older people has sex with someone from a network of mainly younger people, it creates an opportunity for infection to move between two distinct sexual networks.
Over time and with enough points of contact, the chlamydia prevalence in the older, less-infected network will start to look like that of the younger, more-infected network.
This is, of course, only an illustrative example: But in our hyperconnected world, the chance you'll sleep with someone quite different from you — older, younger or something else entirely — is greater than at any point in our history.

Their use or lack of is an excellent predictor of infection rates. A recent study of single, heterosexual men in Australia found only 35 per cent used a condom at their last sexual encounter with a casual partner. There were also notable differences by age: Instead, older men relied on vasectomies as a form of contraception, which, alas, is ineffective for preventing STIs.
Another study found even for younger people who used condoms, nearly half had done so incorrectly, or experienced slippage or breakage. These issues could be undermining the effectiveness of condoms to protect young people against STIs. Meanwhile, although gay and bisexual men have historically reported quite high rates of condom use, in recent years this appears to have declined.
A report from the Centre for Social Research in Health found while 68 per cent of gay and bisexual men surveyed in always used condoms with casual partners, the proportion had fallen to 47 per cent in Condom use undoubtedly plays a part in rising rates of STIs — but experts agree it doesn't tell the whole story.
How much do you know about sexually transmitted infections? In , Australia recorded its highest number of short-term visitors, with more than , backpackers.
Travel can move infection from one part of the world to another. But more than that, people caught up in the joys of travel tend to engage in practices that put them at risk for STIs.
This includes the use of drugs and alcohol, having new or multiple sexual partners, and using condoms inconsistently.
