turbo - thanks for sharing. From a psychology point of view it is certainly explainable although I won't bore everyone with the psychobabbling details. Suffice it to say that "excitement" can be positive or negative (such as "don't get excited - I didn't mean that" where "excited" meant all riled up). So in the same way, when one gets all riled up over vomit....that rush of adrenalin....it's very easy for the brain to confuse it with other sorts of positive "excitement."
kyle - I know you mean well - but I don't think anyone is sugar-coating anything. We are not "normal" and emetophiles are not "normal" either. None of us is normal or we wouldn't be here. We just all have to remember not to start thinking that we are less abnormal than someone else. Actually, in my work in family therapy when it comes to sexual arousal I do declare there ain't no normal.
