Now in this society, we see a lot of MBA (married but available) people
for ONS, affairs and other sex-related relationships and also
SBA (single but
attach) people as well. 
I can say that I have many MBA and SBA friends flirting and ONS and
even commiting adultery around their partners with people that they
know (bosses, good friends, or strangers). Whether it is for their
career - promotions or to get the job; their deprived sexual life -
spouse having affairs, they also want to have one; and other
issues.
Does this be common future for all or just the minority of them
all?
