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.
“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]
“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.
Regarding modern stories about kisses, there’s this story about the kiss of death. Originally reported as being due to a peanut allergy, it has been changed to death from asthma attack.

In Batman And Robin (1997) Poison Ivy kisses Batman and Robin and it makes George Cloony and Chris O’Donnell horny for her.
So there’s…that.
