I notice that you are saying that masturbation is good for the health, except when it is too frequent (it makes you deaf ;-)
What was that, you'll have to speak up! ;D
Sometimes I wonder if we are "bad" at relationships because of who we are, or because of what we have been conditioned to want. I am quite certain there are differences, but I think that we are affected by our surroundings and it impacts on us differently from one to another. For instance, I might be heavily influenced by an advertisement for something, where the same adverts makes no impression on you. Maybe we have a predisposition to be more or less affected by conditions, in the same way alcoholism has a genetic component to it?
