There are several, sometimes competing things that are "human nature". It is definitely HN for males to hunt for various things, including female companionship/love/sex, and it is definitely HN for men to lose interest, (slightly or much more), once the "prey" has been caught.

It is also HN for women to hunt for the best male available to them, but they tend to not be so obsessed w/ the hunt and more interested in hanging on to what they've bagged if it's good. These distinctions can get blurred because both genders are vulnerable to falling in love, in which all bets are off w/ the hunting thing. Both men and women get bored in relationships and stray.

The biggest difference, IMO, is the "thrill of the hunt" deal for men, and it is worse for some men than others. Some have no problem being faithful forever, and some can be in a relationship or married to the love of their life and still need to hunt. Once we get what we want, the passion dies down a little no matter how attractive she is. Women seem to get more attached, not less, once the man has been bagged/caught.
