Getting Closer. I Think ?

Right
I read Darwin's excellent post titled Relax,Relax,Relax. This post has been the most benecifial to me but it now leads me to another question.

I wont go through the whole session just to say I got to a stage were I could inhale deeply with the slightest of contraction on my Helix and could feel it brush against my prostate. I would hold that breath then gently release. Did this several times and my penis became very very hard. It also felt like I had goosebumps in my scrotum. This stage happened 3 times and all very pleasurable and I followed Darwin's advise to relax and enjoy the feelings.
Now my questions?

1/ I got the above stage and I relaxed. Really I did but I could not take it further. I had no sudden warm feeling so what was this I was experiencing?

2/ Darwin you say no more than an hour per session. OMG I was enjoying the feelings that much I was at it for 3 hours. Is this wrong thing to do? It takes a good half hour to get any feelings as it is?

After what I felt this morning all i want to do is do it again. This thing is like being addicted and you want me to leave it alone for couple of days?

I'm now having trouble doing the Key Sound because I'm suppose to leave the Helix alone. Hmmmm not easy to do
