The class members are easy to identify and there ought to be little or no disagreement. Pleasure-based crossdressing is defined as wearing garments of the opposite sex in order to cause a feeling of pleasure. In this variant, pleasure is the primary or driving motivation. Pleasure may accompany other conceptual variants, but, in a peripheral way. This would not cause one to classify the crossdressing as pleasure-based simply because some amount of pleasure is an accompaniment.
Pleasure has to be the goal or primary purpose.
Pleasure-based tactile crossdressing proceeds from pleasure derived by touching or otherwise sensing clothing of the opposite sex. The most common example might be a person that simply loves the feeling of soft, silky things like nylons. This is not a sexual type of pleasure. It is simply a sensual type of pleasure. A person who loves bright or pastel colors might derive pleasure from female clothing because of the rich colors compared to male clothing.
