Well, it’s gramatically masculine but I don’t think it’s exclusive to men: the word was used to describe “Mademoiselle Giselle” in Václav Neckář’s song of the same name so it’s a generic masculinum like some professions. Maybe “cuddler” would be more correct?
BTW, most of the rhyming words that end with -zel are verbs in first/third person singular masculine (yes, subject gender matters with verbs), past tense, imperfective aspect, class 4, type sází. This language is fucking insane.
