Thanks very much, yomo:
While I was reading your post, I was thinking how conditioned I am to "forcing" just about everything in my life, and what this practice means to me. I was able to practice again today, and made it a point to spend some time relaxing and just enjoying the experience, and not feeling like I was there to "do" something (that may sound funny, but I know what I mean
While beginning with valley breathing, and relaxing while laying on my side, I began to feel the buildup after about 20 minutes. I made my mind up to just relax into it, and guess what, my son came home unexpectedly, banging doors and startled me right out of my practice. I fell like a lead balloon.
The important thing was I felt the vibration as I was making the key sound, and I haven't really felt that before. I think a big issue for me is seperating my idea of sex with ejaculation from this practice, and learning how to approach it mentally.
