Are you ready to have sex?

It can be difficult to decide whether it's the right time for you to have sex. You should know that whatever anyone else might say, the decision to have sex for the first time or anytime is YOURS.

Be clear on consent

It is important that sex is always consensual. This means being conscious enough and safe/comfortable enough to say yes to any type of sexual contact, whether that's talking about sex, touching, or taking part in sexual acts. It's about both parties feeling actively excited and comfortable in a sexual situation. Remember you can change your mind at any point, whether that means saying "no" or stopping any kind of activity.

Contraception choices

If you are thinking about having sex and you don‘t want to become pregnant then you need to use a method of contraception. Most methods of contraception will not protect you from sexually transmitted infections so whatever method you choose you also need to think about protection (avoiding getting a sexually transmitted infection). For this you'll need to use condoms.
