Right for the Night

Every new partner brings new sexual health risks, and if you don't use a condom you're asking for trouble (and maybe a baby). Remember oral sex carries risks of sexually transmitted infections (STI's) too.

Check for other STI signs such as inflammation, sores and pain on intercourse: condoms don't protect against all STIs so you need to use your brain before you use your body. If in doubt, don't.

Many STI's don't have symptoms, so getting tested is the only way to ensure you're free of infection.

If you want sex to feel loved or boost your confidence, you're unlikely to be satisfied by sleeping around. After all, you can easily give yourself an orgasm without any heartache. Only have casual sex if it's not going to upset you.

If you choose to have casual sex, some people may judge you for it. Think carefully about who you tell about your lifestyle: but do listen if friends say they're concerned about your behaviour.

Going home with a stranger has risks. Make sure a friend knows where you're going, who you're going with and when you'll be back – and don't invite strangers back to yours. Otherwise you could find your phone missing in the morning – or worse.

Lying to get someone into bed is unfair and can lead to trouble. Whether it's a reputation or a teary ex, bad things come from lying to get sex.

If you know someone, you're more likely to have mutual trust, affection and respect – and that makes for better sex. Don't pick someone who's in love with you for casual sex though – that's unfair on them.

Casual sex is about both people having fun so make sure they get as much out of it as you do.

Only have casual sex if you can do so while maintaining a healthy sense of self esteem. Healthy sex doesn't make you feel bad afterwards: if you do, think about whether the sex you are having is right for you.
