If you are unsure what defines consent here is an outline from the Sexual Assault Prevention and Awareness Centre: "Consent is when someone agrees, gives permission, or says "yes" to sexual activity with other persons. Consent is always freely given and all people in a sexual situation must feel that they are able to say "yes" or "no" or stop the sexual activity at any point." 1.When you’re engaging in sexual activity, consent is about communication. And it should happen EVERY time. 
2. consent for one activity, one time, does not mean giving consent for increased or recurring sexual contact.
3. Sexual assault can happen in marriages not just one night stands.
4. Finally remember you can withdraw consent if you no longer feel comfortable.

Remember sex without consent isn't sex.
