No. It is not uncommon for adults to dress up in uniforms, costumes or other outfits and role play as part of a healthy sexual relationship. Most Furries do not own costumes and many take no interest in costuming. Those who are interested in costumes often own very expensive custom created Fursuits. They are often very proud of the quality and construction of these Fursuits and are unlikely to engage in activities that would harm the quality of the costume or the image of their character. Chances are there are many more people being intimate in an animal costume each day who are not Furry than there are Furries willing to take a similar risk with their characters.
