I think it's all about how educated the person is with this disease. Having an ostomy is life changing and the struggle they go through is also different from person to person. I do not have an ostomy but I would certainly hang out with someone to figure out how it affects both. I have been a Crohn's colitis patient from 13 years and I have such low confidence to be in public many times. Also, remember rejection outright is better than someone giving you false hope by using you for time being.
