They should probably feel akward: they just spend a few hours having very very enthusiastic sex, an effect from a strange toxin.
But they can't : they are very happy no padawan was there, or ex-padawan, and they were friends before: it's more easy than if they had sex with total strangers. They're all adults and, strange circonstances or not, it was very, very good.
They can do it again sometimes, or not, but it became a private joke between them.
