I don't think I have ever been afraid of loosing my medfet or that it will diminish from lack of fulfillment or from over-exposure. As with all human interest, our interest waxes and wanes at time , it only natural with everything in life . At the beginning, its all exciting and new and its only natural to be enthusiastic , intrigued and captivated by new experiences , discussions and interacting with fellow enthusiasts as it becomes our passion in life at that point in time.
After this initial high we can lose some interest , this is because everything in life is in a dynamic flow, that is every changing and the changes make us change too. Sometime the changes hit us hard and that makes us a little down or lose interest; this is further compounded with the daily stressors of our life , work, relationship, free time etc .
In addition what initially started as a passion can become so consuming and the more you compare yourself to others, you can begin to lose all interest and get into a negative spiral. A very excellent and appropriate quote comes to mind by Theodore Roosevelt "Comparison is the thief of joy"
For me personally I done most of what some dream of doing and continue to do on a daily basis so its not an all consuming passion. I still enjoy my medfet because from the start of my medfet journey I had a clear idea of what I wanted out of this experience and that has not waned and I don't expect it too. But everyone's own personal journey is different , individual and unique and as such how we react is unique and individualized.
I never felt ashamed, embarrassed or guilty to have a medical fetish . As I have said before I think guilt is rather a very subjective word as it implies a feeling of worry or unhappiness that you have because you have done something wrong, such as causing harm to another . I don't think any fetish or kink is wrong , we all have our likes and dislikes , so I look upon mines as things I enjoy and like and I know it does not cause any harm to others but can do the opposite and bring happiness, pleasure and enjoyment to others .
