Zanozotopia

The best sex you've ever had. Defined by the participants of said sex act; meaning that if somebody only witnesses but doesn't participate in the sex act, it is not their zanozotopia. Factors determining the zanozotopia include but are not limited to: Number of sexual partners, hotness of said partners, number of orgasms, intensity of said orgasms, setting, timing, position, length, partner's or own ability, etc...
but any of these categories can prove to be the defining one.
