I've read that males have a different risk to reward ratio (not in every species but in many, including humans) especially in terms of reproduction. One male can in-theory have many more offspring in the same time period than one female, and any gene encouraging that kind of behaviour in the past would probably have been naturally-selected-for amongst our ancestors. Of course the welfare of the offspring will likely be lower in that case but evolution still seems to have still left human males with remnants of a strategy of reproductive risk-taking.
