In an open relationship, both party agrees to sleep with other people besides their current partner.
A general slut is someone that goes around sleeping with whoever they want even if the other person is taken or married or they (the slut) are taken or married. Meaning they don't discriminate.
Please Enlighten me, Is sleeping with many people is called a slut? or you need to y know sleep with many people but you have a non-open relationship?
