Can we lose the magic?

I’ve started the journey there is about 3 months. The beginning was very encouraging, I started to have super pleasant feelings after 3 sessions.

I got to the point where I had amazing, super sweet, very long (like 3 to 5 min) orgasms every sessions. I don’t know if it’s what you guys refer as a super O but anyway I was very happy with it. I tried things like thrusting and touching very slowly my cock and I got some of the best penile orgasms of my life (like crying intense).

The things is all sensations started to fade away at a point where each sessions were less intense than the one before. I’ve read forums and all and learned that thrusting, touching my cock and watching porn could be detrimental. So I stop all of this and tried techniques like the relaxing a lot and “do nothing”, I tried to lower my expectations and enjoying the present moment. It is most of the time kind of enjoyable, I have involuntary contractions and trembling very quickly, but nothing comparable to what I had before and I feel quite frustrated.

Did anybody go through a similar situation? If so, how did you get the magic back?
