WePow, I understand the thought behind this suggestion, . It would be great if eventually Lava could bring those NEEDS that he feels toward his T into his relationship with his wife, where he can learn to get these met by her. However this is different to acting out his sexual fantasies for his therapist through his intimate relationship with his wife. This should stand alone, for what it is, a healthy sexual relationship with a woman he truly loves. This deserves exclusivity. I don't believe it's healthy to bring fantasies for another person into a marraige. Certainly not during sexual intimacy with a spouse, the focus in this moment should be on them, on the relationship that already exists. Otherwise you allow space for discontentment to set in.

Just my opinion.
