Jealous of wife and its therapist: should I worry?

When I had to report my t for exploitation and abuse, they took my hard drive . They certainly did find content like that.
To the OP. I would venture to say that most therapists will not cross that line. Some do , though. Maybe get her to open up about her therapy to you. But I would assume she'd probably never disclose these sexual feelings to you.

The first question that came to my mind reading this thread: why are you looking into her phone? Does she know it? If not, maybe something to address for you?

It sounds like her curiosities and fantasies actually improved your sex life, which is probably a positive. I think jealousy and an anxious reaction to the unknown are natural, but so are sexual fantasies with a broad range of content and targets. I think you are also doing the right thing not interfering with your wife's therapy experience much despite your discomfort.

Maybe one way of improving the connection and directness between you and your wife could be talking about your recent changes in your sex life together? I guess you could tell her that you are pleased and ask what made her interested in those acts recently. Ask her how they make her feel, what her experience is like, what kinds of fantasies she has. I think that people often hide sexual fantasies from their partners especially if they include other people, because they feel they are inappropriate and would hurt the partner. I think a lot of it is how they are presented - I can't imagine any adult who never had fantasies about people outside their primary relationship, maybe about a new colleague or someone they do a hobby with - they can last for a while and then dissipate. I do not agree with the notion that, if a marital relationship was perfect, people would never have fantasies about others. I personally had lots of wonderful conversations with romantic partners about our fantasies involving other people than just ourselves - it strengthened the relationship and trust rather than breaking it. When people experience this in therapy, it is often described as erotic transference and analyzed and interpreted as having deeper meanings not necessarily related to sexual/romantic desire per se.

On your concern whether your wife has an actual affair with the therapist - those things do happen, not frequently though. Much more common that people develop these feelings and they remain feelings, either shared with the T or not.

Me!!!!

It isn't love , but it is a very riveting feeling. The T is going to put uo boundaries and walls, and you will see this enchantment become disillusion at some point. No one can meet all of another person's needs, but at first it seems like the therapist is going to, but his job is to give her the skills and comprehension to find it back in her real life with you. It's a process.

I never did it and it happened as a mistake, then I continued to read for a couple of days, while I rationalized and, then, solved by talking to her (because she understood that I had some problems and was willing to help).
Anyway, since I never do it, it was not a way to send me hidden messages.

I am quite comfortable with fantasies and I don't want to control or stop her mind, which I think is impossible and counterproductive. And it is an abuse.
It is important to have good communication to understand situations, wills and prevent crisis.
That was my main concern in this story: I get acknowledged of something strange and I knew it came from something I felt being kept apart.
I suppose you may understand that my mind made automatically a pessimistic 1+1 and I needed my best self control (and a "comfortable and safe" 3500 miles distance...) not to ruin everything.

Yes that is what we started doing.
I am very happy about that and also a little "scared" to make mistakes, but it will be very funny experimenting together...
