a dong sniffer is a neat freak gay man who sniffs a cock before giving a blowjob. This isn't unlike a straight guy who fingers a girl and smells the result before going down on her.
church hurt is where you experience a degree of distance, pain, or judgement from your church community. Essentially, you are just unable to “find your place”. This is prevalent in the Christian community, but can be extended to other religions.
