Why do I feel like a pedo?

you are right to feel disgusting, because that is. i presume with your use of the word pedo you are american. One thing you need to understand is that paedophilia is non discriminatory and affects all aspects of the human family, gay, str8, bi, trans etc. etc etc. I would in your situation seek counselling of some description, because your feelings are abnormally disordered, and they are illegal. do something before it turns into a problem.
