I think I'm a sex addict

Hi, I am a 30 year old woman, and I think I have a problem with sex addiction.
For some years already I have been experiencing difficulties restraining my sexual lust and needs. There is not a minute in the day when I don't think about sex and I do everything I can to get it. I have had multiple sex partners and I am currently in 3 different relationships and still going for more in order to satisfy my needs. I am losing control of my life and my behaviour will hurt those people, I know it and I care about them but still can't get enough. I feel all alone with this, I can't talk to anyone and need to be lying to people I love just in order to have more sex.
I want to stop but every opportunity I have, I take...

Thanks for your answer, it feels like it's the first time I'm being totally honest for years and someone can hear it without judging... It means a lot...
I don't have any bipolar disorder, or mania that I would know of. I think it has been like that since my sex life started but back then it just passed for big sexual appetite and served me well. I was in two longer relationships (4.5 years each) and was able to get enough out of them for the 4 first years, but they both ended with me losing it and cheating after too long period of being apart.

No I have not, this forum was already a big step for me and and I don't know if I am ready to speak about it face to face with someone

Yes it's exactly like that... And I know it will hurt them and others but still, when I get the chance nothing else matters at that moment. I feel totally comfortable when I am spending that time with any of them, it's feels good and right until I am alone again. I am sure you're right and I should see a therapist but I am so scared. If I would tell anyone they would just think I am a slut, not that I have a problem. I have been thinking it myself...

I also think that there is nothing wrong with your thinking or feeling this way. I think you definitely have a higher sex drive and I would also consider it an addiction since it is constantly on your mind and affects other daily activities.

As Snaga has said, there is probably a lack somewhere. Therapy can definitely help or you can do a lot of soul searching which would take much longer. My guess is that you may get bored with relationships after a certain point or perhaps you enjoy the novelty of a new partner.

Thanks a lot for the feedback.
It is helping me already just to be actually discussing it with people who don't judge and try to understand.
I think maybe I feel like a different person myself when I am with these different men. But no matter how many of them I am definitely not satisfied by the amount of sexual encounters...
