I think they “affair down” when you take in the whole package. But as WWTL noted, most of the time they are not looking to replace what they have. They want something else.
I listened to an interview with Dr David Buss and he described long vs short term mating strategies. And how people change their priorities based on what they are looking for.
The short term list sounds, to me at least, very similar to what many WS are looking for….
And I get that this does not describe everyone or every situation. Had to get that in there to head off the “Not all X are like that!”
Dr. Buss studied 33 cultures and found the following:
Both genders desire the following in a long-term partner:
* Intelligence
* Kindness
* Health
* Emotional stability
* Reciprocated attraction and love
Women prefer these characteristics in a partner:
* Social status
* Ability to garner resources
* Hard work/ Ambition; long-term resource trajectory (potential to gain social status, resources etc)
* Women also have a filter in which they will more likely choose a man who is desirable to multiple women
Dr. Buss says women prioritise these characteristics due to asymmetry in sexual reproduction (ie, pregnancy in women, need for resources, safety, protection as women bear the burden of pregnancy and child-rearing etc)
Men prefer these characteristics:
* Physical attractiveness (eg, clear skin, clear eyes, symmetrical features, full lips, lustrous hair, waist-hip ratio etc)
Dr. Buss also says that as men get older, they prefer younger women (ie, he gives the example that younger men prefer women around their age, but by a man's 2nd and 3rd marriage, the age gap widens as older men prefer women increasingly younger than themselves)
Short-term relationships:
* Women prioritise sexual attractiveness/physical attractiveness in men and also attracted to men who are "bad boys" for short-term relationships
* However, men drop their standards for physical attractiveness in women if it's a short-term relationship for sex only
In regards to cheating and infidelity:
* Women tend to cheat with one long-term affair partner whom they develop emotional intimacy
* Men tend to cheat with multiple affair partners and have a "carpe diem" approach, meaning that they tend to cheat if opportunity arises in a transient way
Both men and women put great importance on emotional stability, intelligence and kindness for long-term partners.
What is interesting here is that for short-term relationships and hookups, men drop their standards for physical attractiveness WHEREAS women prioritise physical attractiveness for short-term relationships.
Also women tend to want "bad boys" for short term relationships but for long-term relationships they choose the guy who would make a "good dad" type.
