I took the advice that you should focus on just one or two files rather than overwhealming yourself. After a few listens to TrigHardOn, I found that I could trigger myself with something like 15 seconds as the delay and have an orgasm.
Funny thing, it doesn't really give me much of a hard on, although the sexy image I chose does tend to pop into mind. I suppose this is because my real goal for a long time was just to orgasm from hypnosis.
The second file I focused on was the enchanted keyboard curse because it's sort of like the genie in the text editor. I was very skeptical about being able to just type up any situation and have it come true, so I kept every attempt modest at first.
The first thing I knew would work, was to launch TrigHardOn using the keyboard. If I can say it and trigger myself, why wouldn't I be able to use the enchanted keyboard? It worked perfectly so I kept adding simple suggestions each day. Every day I use, "I am easier to trigger every day and more helplesss every day. the end", for good measure.
Holly crud! After a while I had invented a mistress who would rape me sitting at my desk at work. I didn't really control when that one fired for one day and it kept coming back. It was a bit tough to get my work done, so I unplugged that one.
As far as I can tell, this stuff is like Yoda says: "Do or do not. There is no try". I have hesitated to push the envelope too far at a time, because I'm afraid that too many failures will make me lose by belief.
One thing that seems to help is suggesting (via keyboard) that I will observe what the trigger does from the outside, watching my reaction without any preconceived idea of how intense it will be each time. This is combined with the suggestion that the trigger gets more intense every time and is not expected to hit full power immediately. A partial success then becomes expected. The day I did this well my reactions started quite mild and ended up really intense.
Hope this helps you in some way. You can succeed if you are patient.
