look up any word, like blumpkin:
Multisex. A partner in a strong relationship, who wants to have sex or realatinship with other men/girls, and both partners are agree on the matter. They both like multisex.
Multisex :
I both are agree to praktise sex with other ppl, then it's multisex

If not both like this idea, then the partner who praktis this, is unfhaitful.
