Why give consent?
To give consent means to give permission. For example, if someone wants to touch you, have sex with you or kiss you. Even during sex, it is important to check with yourself whether you still want to. And after sex, think about whether you still feel good about it. This way, you ensure that sex is a good experience for both of you.
Consent is something you do together. So it is not only important that you give consent to your sex partners, but also that you ask for their consent.
