Kissing scenes or intimate scenes is just not compatible with marriage.
Regardless of the fact that its a job or "acting",
when you are in a relationship or marriage,
there are things which you treasure as only something that can be done by the both of you in the relationship.
To exploit that treasured acts of intimacy elsewhere outside of the relationship will of course cause hurt and bad feelings for the one who is left behind having to watch his lady or her man "perform" the same thing with someone else.
Think about it carefully,
its not really about trust,
its about respecting your partner over your craft/art/job.
If you think your partner is more important than your craft,
then sacrifice that part of your craft.
sacrifice that PART of your craft.
I didn`t say sacrifice your craft,
but only that PART of your craft.
So continue acting and omit intimate scenes out.
Yes it will undermine your career but that is exactly what prioritizing one thing over another does.
On the other hand,
if you prioritize your craft/art/job over your partner,
tell him or her so first,
then if he or she accepts that,
then all is well.
But the effects in this flip side is that your relationship will never be as solid because you have expressed that its 2nd in priority to your job.
Which partner wants to feel 2nd best?
It surely would have its own psychological effects.
the answer to this controversial question is priority.
Which will you prioritize.
Make the choice and make the sacrifice.
You can`t have your cake and eat it i.e.
you can`t have two things that are incompatible together.
