all of that, and people lie on these kinds of surveys. also, people lie to themselves constantly about relationship status. 'we are currently fucking' is not objectively definitive and is open to personal interpretation.

and don't forget conditioning/momentum - "sorry i have a boyfriend" is the automatic reflexive response of a 20-something female, for a huge variety of contexts, regardless of whether it's true or not.

it's like 10 different statements rolled into one.

either way, i suspect that yes, a lot of young women are all in 'relationships' with the same subset of guys in the 25-45 age range who are cleaning up the scene and loving life. there's never been a better time to be an attractive male.
