This is a huge problem, too often overlooked. Simply being in a relationship isn't a 'free sex whenever you want' card. Consent is still applicable, always - in a friendship, in a relationship, hell, even in a marriage. Sex should ALWAYS be consensual. So many people erroneously think that because they are dating someone - and moreover in a committed relationship with said person - they are granted 'sex privileges'. It doesn't work that way. Glad you posted this, because we need to spread awareness about this.
