Okay, so the raws basically confirm that this magic means the feeling of sex :
その味を知る者は私の魔法からは逃げられない
"味を知る"
According to several translators (and damn good ones at that), the above line directly says those who had sex. Although we should probably wait for the official translation (which comes out tomorrow) for confirmation.
That said, if this is true, then holy fuck, this is borderline hentai.
It was already obvious and the people who defended it (including the translators )tried to damage control. But it´s unmistakeably meant to be sexual pleasure.
Implying sex is nothing new to Mashima he has done this back in Rave alot as well, but in his good series, it was always used during calm moments where the cast sat around a campfire or was throwing a party not during a war.
