Masturbation :: How Much Is Too Much?

IF you have read my previous article, you would know one of the problems I was having...i.e. I couldn't masturbate the way most males do. However, I managed to fix that one by just giving up my old way and doing this. However now, this is one of the greatest feelings ever, and I keep wanting to do it. Not to the point where that's all I'm thinking of but you know, you get home and you're on the computer and next thing you know. But how much masturbations is honestly too much? is once a day too much? is once every three days too much? also, would too much masturbation cause you to be unable to ejaculate with you gf?
