ladies' man

this term is problematic because there is no precise equivalent for women ("gentlemen's woman"?) and because of the use of "ladies." The lopsided and unattractive "parallels" for women would be the pejorative "femme fatale" and "man-eater." Some alternatives: popular/successful with the women/the men, heartbreaker, hottie, smooth operator, God's gift to men/women. See also femme fatale, lady (n.), philanderer, playboy, womanize/womanizer.
