Hello Andu: I see this is your first post here on PC. So... welcome to PsychCentral! I don't know if you're here simply seeking advice with regard to this particular concern, or if you plan to hang in here with us. However should you be planning to continue on, may I suggest you introduce yourself to the general membership over on our New Members Introductions forum? Here's a link:

I'm afraid there's not a lot I can tell you about what you're experiencing with your gf. You asked if she should see a psychologist. I'm not a mental health professional myself. So this is just my personal opinion. But I would say there is probably no need for her to see a psychologist in particular. However there might be some benefit to her seeing a mental health therapist. (I see though you are in Albania & I don't know how mental health therapy is provided where you live. Perhaps where you're located, psychologists are who one sees for mental health therapy?)

This situation is a bit complicated though, to my mind. It would really only be of potential benefit to your gf to see a therapist if your gf sees a need for it & wants to. And probably, I would surmise, your gf would only see the need for it if she sees her preoccupation with sex to be problematic. (From what you wrote, it doesn't sound as though this is the case.)

As long as the two of you are together, & if you're okay with it, then perhaps there really isn't a serious problem here. At least not at this time. However, should your gf's preoccupation cause her to begin engaging in risky sexual escapades, her preoccupation could certainly become problematic... perhaps even dangerous. Even so, though, you can't pressure her into seeking therapy. It will only be of potential benefit if it's something she sees a need for & wants to do. Plus... sometimes a person has to see a few different therapists before s/he finds one that feels comfortable. (Not every therapist works well with every client.) So your gf would, potentially, need to do some searching to find the right therapist (or psychologist) for her.

Here are links to some articles, from PsychCentral's archives, that may be of interest. Hopefully some of the information in these articles may be of help with regard to understanding what is & is not considered to be sex addiction & what can be done about it:
