"If I accept that a women's participation in these acts is a show of love or being 'into' a guy. Is there then an assumption that women do not actually enjoy these acts for the act? That it's always about showing love or dedication? About pleasing another person?"
Through the years I have read that the WW never did
anal before the affair. Two main reason for the
WW allowing anal (or other sex acts never done
before) during the affair was that the OM pushed
for it and the WW wanting to keep the OM caved in.
Another reason the WW in marriage could not let her real sexual side out because she did not want
to let her BH to think poorly of her.
Madonna/Whore Complex.
All the BH see's is that his WW gave the OM
things she always refused to give him.
Why does the BH do hysterical bonding?
The BH is sexually reclaiming his WW back from
her OM. Sorry having a WW stop having sex and
going NC with her OM for the rest of her life
only stops any more sex happening between the WW
and the OM. This does not provide any sexual
reclaiming his WW back from the OM.
So if the OM got anal. The BH needs to reclaim
that part of sex back from the OM.
If once a night was enough for the BH pre affair
and the OM got it 3 times. That BH is going to
tell his WW she's doing it 3 times in one night,
maybe 4 times. Even if he has to over dose on
vitamins. And if the BH fails, oh boy. Now the
BH has to accept that his WW cheated on him, and
the OM was better than him.
And the BH stays because he does not want to be
a part time dad, have kids grow up in a broken
home, lose his house, take a financial hit,
retirement plans gone.
Eventually with time he does not trigger often,
the triggers pass fast. Marriage may recover,
maybe stay in limbo.
