Most Helpful Guy
In previous centuries, culture had dictated that men must do the asking, and women must choose the males suitor they will spend the rest of their lives with. Naturally, the unsatisfactory men would be the ones rejected when the woman gets her pick (though in a much more vague sense, a woman is technically rejected if she were never courted by a particular suitor). In today's society things have evened out a good bit, but its still heavily skewed towards men having to do most of the asking, and women do the choosing. So yeah, still men rejected more often.

Men. They put themselves out more then women.
