Sex is assued in most dating circuits-mono and poly alike.
But-that doesn't mean one can't be poly and a virgin.
It might be awkward. But-whatever. Being poly in a mono world is awkward. Being bi in a hetero workd is awkward. Being a woman in a mans world is awkward.
I think there's nothing wrong with identifying ones ability to be romantically loving with more than one person before having had sex with anyone.
