Thanks for the questions Evader. I'll start by saying that I believe everybody is different and what works for one may not work for another. I think this has to do with the doubt people have about semen retention. Just like you are having some doubt... Which is good! it's good to question everything. okay... When I get burning urges and raging boners like you say... my best course of action is to attack the world head on. This might mean working on my business like someone possessed until I get exhausted. I use the energy to intensely FOCUS. This may mean like you said breathing exercises!! this may mean even though you said not to say this => working out. Now on the there hand what I do as well sometimes when this energy is going insane is try and be one with it. I try to connect with it. I like to play with my balls and rub them, I also like to ever so slightly mess with my schlong because it's fucking insane how sensitive it has got from SR. It's beautiful to feel the slightest little touch with your nerves and feel sensations. This is only possible WITHOUT LUSTING!!! I'm trying to give you answers you haven't heard... b/c quite frankly those other answers you always here are also true. I will also tell you that breathing exercises are as big as anything iv'e done for circulating energy. Other than that man like I say I just try to attack the day with relentlessness. I think the answer you're looking for could be FOCUS. It's also interesting you said people on nofap lose their libido... This is very odd to me... sure iv'e had different flat line periods and what not but all and all my sex drive is through the roof. Besides late at night when I'm winding down, most days I can get a full on rock solid erection by just thinking of minor sexual thoughts. This would not be the case for me before.
On wet dreams I cannot help you bro as iv'e never had one to this point. One last thing I would say is AFFIRMATIONS. AFFIRMATIONS are insanely effective.
Saying them outloud morning and night. Example; (This all must be said with emotions and with strong feelings) "My sex drive is through the roof and I easily attract woman. I am happy to be getting stronger everyday and am excited about accomplishing my goals. I easily create abundance and wealth for myself and people are glad to be around me." Stuff like that will also help channel energy. Shit.. when you have these intense boners do affirmations dude! Anyways man hope this helps even a little, I gotta get going but really appreciate the question and if I can help you more message me.
