English: When you’ve sex with other people, it’s crucial that both you and your sexpartner(s) are on the same page on what you want and what everyone else wants. Always ask before and during sex for your partner(s)’s consent. If your partner(s) doesn’t answer your question with a “yes”, it’s most likely an indication that they’re no longer comfortable with the situation, and a sign that you should stop. Consent can be withdrawn, at any time, during sex!
Indications that someone might like to have sex with you can be kisses, taking initiative, touching, getting undressed, (pleasurable) moaning, etc. Your partner(s) should actively be showing that they’re enjoying themselves. Consent isn’t about how a person’s dressed or other appearances, but about reactions to a specific moment and expressing a wanting for it to continue.
A yes to wanting to have sex doesn’t have to be verbal and neither does a no. Less eye contact, lack of touching or fewer kisses are examples of signs that your sexpartner(s) might not be in the mood for sex (anymore). If something like this happens, or if you think something might be wrong, ask your partner(s) if he/she/they want to continue. A person can at first agree to have sex, but later change their mind. It’s okay to change your mind about sex at any time and you never have to do anything against your will. Always respect your own and everyone else’s right to stop a sexual act if it doesn’t feel right.
