I think that kisses having magic powers is just something of a general theme for stories at the time and place that the Brothers Grimm were collecting folklore, not something gender-specific.

en.wikipedia.org/wiki/Sleeping_Beauty

“Sleeping Beauty” (French: La Belle au bois dormant, or The Beauty Sleeping in the Wood;[1][a] German: Dornröschen, or Little Briar Rose, Italian: La Bella Addormentata), also titled in English as The Sleeping Beauty in the Woods, is a fairy tale about a princess cursed by an evil fairy to sleep for a hundred years before being awakened by a handsome prince.

The version collected and printed by the Brothers Grimm was one orally transmitted from the Perrault version,[10] while including its own attributes like the thorny rose hedge and the curse.[11]

There, it’s a prince’s kiss that breaks a curse.

en.wikipedia.org/wiki/The_Frog_Prince

“The Frog Prince; or, Iron Henry” (German: Der Froschkönig oder der eiserne Heinrich, literally “The Frog King or the Iron Henry”) is a German fairy tale collected by the Brothers Grimm and published in 1812 in Grimm’s Fairy Tales (KHM 1).

There, it’s a princess’ kiss.

EDIT: Though I suppose one could take issue with the disproportionate-to-population level of royalty involved in doing all this kissing.

EDIT2: You know, oddly enough, I’m racking my brain and I can’t think of present-day legends and stories where kisses do magical or supernatural things. There are some characters I can think of where a kiss might have some incidental effect — I’m pretty sure that I vaguely remember there being some Marvel Comics X-Men story where Rogue kisses her boyfriend and puts him in a coma, as an incidental effect of skin-on-skin contact. There are some kiss-adjacent things, like vampire stories where a kiss segues into a bite on the neck. But magical kissing seems to be out-of-vogue today.
