Hey there! What a great discussion you guys have here! I felt the urge to share my experience with someone who's actually into this subject and ask for advice =)
I have been practising semen retention for more than an year, and although I haven't reached more than 42 days in a row during this period, I am very much pleased with my accomplishments: during last year I have ejaculated 16 times, which is a terrific improvement when compared with the previous year: more than 300 times for sure...
Of all these 16 times only ONE was on purpose, and it was the 16th, on 18 December. I am actually quite glad I did so, because now I feel with an invigorated motivation and determination, and I have realized that it is a LOT about a state of mind and not simply wanting it.
I'd like to start with the few changes I felt.
I have become in general more sociable, I sometimes can run a lot without feeling as tired as before, my grades in college have improved, on the other hand, my insomnia have increased (which is not nice obviously...)
Another interesting thing, is that now I become conscious during sleep several times. Some would call it sleep paralysis I suppose.. But it's quite interesting: when I am in this state, I can freely move the energy in my body, and the consequences are remarkable. If I tell the energy to go to my arms, I will feel them lifting in the air, if I say to my legs, they will lift as well (when I say lift I don't mean my body, I mean something else, my astral body or whatever), if I think of my belly I will feel warm in there, when I tell it to go to my head, I feel a rather uncomfortable pressure in my head and nose bone, but curiously it will lift as well and sometimes to the point that I can leave my whole body for instances (fascinating!). Now at last, if I think of my penis, guess what... Ejaculation!! Ahahah it's fascinating xD
Now I'd like to ask for advice. During this year I had a few periods when, I now realize, I was celibate. But most of the time I wasn't, I would masturbate and stop just before the point of no return (some call it edging), I never watched porn but watched stuff quite close to porn... After this last time (the 16th) I finally understood and assimilated what I believe to be the state of mind required to achieve a longer period. But, I want to do it safely.
By not masturbating neither physically nor mentally I believe I am making it safer and healthier. But still... What should I do to be successful? By successful I mean: being celibate for a considerable amount of time, say 100 days, without getting physical/mental injury, without getting angry, mad, depressed...
What I do now is: before sleeping I try to quiet my mind for a while, then I will draw the energy up with my mind and pelvic muscles. Since I don't think I can successfully bring it down with my thought alone, I do the microcosmic orbit next. I also do standing meditation (Zhan Zhuang) and try to draw energy from the earth (my purpose is to balance my yang energy with yin energy from the earth). I don't do all of this every time, and I change a lot the order.
The problem is: I dunno if this is the best choice of practises, and also I don't know if I am doing these well. I sometimes feel great after this, and I also assure no nocturnal emission. Other times I feel too excited or with energy stuck in my heart, which accelerates it abnormally...
So, I'd really like to learn a simple and safe method to this. Should I simply practise mental emptiness as Safi suggest? If so, how to? Just sit and try not to think?
Hope this thread isn't dead, I would very much appreciate some advice =)
P.S. - I have recently experienced blurred urination, blurred from sperm I suppose =\ any suggestions?
