^ Well, my grandmother liked only Kirk when the Original Series was new (to this day, he and Tasha Yar are the only Star Trek characters in whom she's expressed any interest). And my younger sister almost idolizes him. I doubt that just males who admire the character.
As noted above, perceptions of him as particularly sexually active, notably taken with the opposite sex, or possessed of a maverick disposition are in conflict with the facts.
Captain Kirk probably one of the most upright characters we've seen on screen (and William Shatner apparently played him so much that way that Nicholas Meyer felt compelled to force it from his system to an extent, waiting until Shatner acted less like Kirk and more like a less heroic character before moving beyond some scenes).
