Hi Ts, I understand your concern and we can see how much you value the relationship with your S.O.

You named your thread "Unacceptable Addiction" perhaps due to fear of unforeseen infidelity in the future. But is what your S.O. doing an addiction from his POV? Are there addictions that you might be able to see eye to eye with your S.O.? Perhaps there is an underlying issue beneath the blanket of lust and curiosity.

If both of you truly wish to understand and improve the relationship, seeing a couple therapist might be the answer.
