Supersexual

[Raeanne Dimick]

[Supersexual] is the term I use for mostly straight men and women who value sex for its own sake and are always seeking new ways to express themselves. If you are [supersexual], you have probably had a wide variety of heterosexual fantasies or experiences. But your sexual interests are not confined to the [straight and narrow]. You might refer to yourself as freaky, straight-plus, polysexual, or [try-sexual]. Several studies suggest that men and women who have sex with both genders tend to have more partners altogether, possibly reflecting the stronger and less discriminating (in terms of gender) sex drive of people in this category.
You differ from heteroflexible men and women primarily in the degree to which you are adventurous and actively seeking out new sexual experiences. Novelty itself is arousing to you, and you push the boundaries. When you are horny, you seek relief wherever it can be found.

[Gregory]

That is beyond or outside the sphere of sexuality. Also as noun (with the).
