Ok, haven't written a progress log for a while. Workout remains the same, JP90's program, 2-1/3-1 weekly schedule.
As far as the whole "refraining from ejaculation" thing goes, here's what's happened so far:
I've successfully refrained from ejaculation for about 1.5 weeks (longest interval). It's difficult to not ejaculate while at the same time edging after every workout for 30 minutes. After a while, I started to forego the edging because I knew I would not last long. In the past week, I've edged only twice, and each time I didn't last very long (less than 3 minutes one time, and less than 12 minutes today). I've decided that it's my body's way of telling me that it's not going to cooperate with this kind of "torture" of my senses.
Also, I've noticed that after 1 week without ejaculating, my sleep patterns get messed up; I tend to wake up earlier with less sleep and feel stressed or nervous the whole day. I also find it difficult to focus as my mind always wanders to sex. After about 10 days without ejaculating, I found it difficult to maintain an erection, as I believe my penis has "forgotten" what it's like to ejaculate and kind of figures "Eh, what's the point? There's nothing for me at the end..." At least that's how I think about it. It could also be because of lack of sleep due to sexual frustration (edging every day, but no ejaculation for over a week).
I will probably continue edging, and ejaculate once or twice a week, on my off days. This will help me stay focused, relaxed, and also make sure my "pipes are clean."
