From a general emotional perspective I feel guilt after, anticipation which NEVER delivers, my mood shifts in down gear for the next 24--48 hours after, and i feel weaker in spirit.
I think that your psychological reaction to masturbating is the problem not masturbating itself. That's just weird.
Also, I disagree that doing it really affects anything else. I mean are you guys either so good at masturbating or so bad at sex that masturbating causes you to be less interested in sex? Maybe I need to work on my technique, cause for me it's not even close to as fun as sex.
Perhaps if you have a very low sex drive I could understand the point, but I would imagine for most people it wouldn't make a difference. I mean I'm a two a day kinda guy (sex/jerking off/both, even when with my GF having sex daily I still looked after myself once a day as well), so maybe if I jerked off 4x a day there might be problems, but a) that would hurt and b) who does that?
I guess I just don't see the negatives to it
