So I suppose if it were not adultery (according to your definition), you would engage in swinging? It is your preference not to...since you would most likely not do it regardless of your relationship with God and your understanding of what 'God's Word' is. So...you are guilty of interpreting the Bible in support of your preference!
It works both ways...

The HOLY SPIRIT convicts the world of sin (John 16).
No, I KNOW taking another partner & having intercourse w/ them
is wrong & sinful - I actually knew that when I wasn't a Christian!
& so do the unsaved today.
I also knew sex outside marriage was wrong back then too -
I just didn't happen to care enough to stop what I wanted to do.
It doesn't work both ways - if you can't read a clear passage, the
problem isn't w/ interpretative differences, it's with your inability
to
honestly SEEK TRUTH.

What we have is people who are doing what Satan did in
questioning what we know - "
has God said...."???
YES, He has said it's sin - instead of accepting that, they
try to do word searches & obscure studies TRYING TO SUPPORT THE SIN instead of honest study; taking the emphatic commands
that ARE spelled right out into their consideration.
Instead, they flush the obvious, blatant command down the toilet
to embrace some obscure OT. situation (which is why
God brought a NT - to proclaim the FULL truth that was hidden
to them) & try to call that truth.
(& these are the same people who will claim the OT is obsolete when
you try to use it to condemn homosexuality & other things).
It's dishonest, bias study with a motive to support sin.
*****
The definition of adultery given by Jesus ENCOMPASSES THE OT -
it's Jesus who gave the law & allowed them to commit these
sexual sins becuz of their rebellious, hard hearts; but their sacrifices for 'sins in ignorance' covered them.
BUT GOD DOES NOT ALLOW THIS NOW since He's came to earth & brought the illumination of the FULL mystery of God to us - He tells us the
meaning of that OT Law & gives fullness to it.
This is why it goes FURTHER than just 'letter of law' like they blindly
followed back then & which was veiled truth.
Instead, Jesus shows us that even lusting after another person IS WANTING TO HAVE SEX W/ THEM (& when that lust is continually fed, it leads to them eventually committing the physical act -..
which is how hatred works.
Feed hatred long enough & pretty soon it's being acted on - people commit murder, violence, theft, abuse, etc.)
Read how sin is born & its natural course:
James 1:14-16
14 But each one is tempted when he is carried away and enticed by his own lust.
15 Then when lust has conceived, it gives birth to sin;
and when sin is accomplished, it brings forth death.
