How do you remove hair from around your anus

The scholars state it is recommended to do this as filth can attach to the hair and it is included in the definition of pubic hair. Now I don't wish to use a razor but just a trim - looking in a mirror underneath and small scissors is very hard. If you are unmarried or the wife doesn't want to assist what can you do? Only a doctor if he is examining that area may see it without it being haraam. What other options are available? I can't think of any more.
